RUNNING SHOE SUMMARY
The Adidas Takumi Sen 10 is a racing shoe for those who want a lighter and faster shoe for 5k/10k efforts. The biggest update is the Energyrods 2.0, featuring a lateral extension in the midfoot (similar to the Boston 12) which adds mild medial guidance and a bit of extra stiffness for those who land there. A similar, light upper sits slightly snug with just enough room throughout the length of the foot, providing a secure, racing-style fit. Best for those who want a moderate amount of stiffness, a lighter ride (albeit with a slight weight gain from the prior version) and a surprising amount of Lighstrike Pro for intervals, shorter tempo runs and 5k/10k races, the Takumi Sen 10 stays remains consistent despite a long history of changes.

FIT
The Adidas Takumi Sen 10 fits me true to size if a tiny bit short in my normal US men's size 10. The volume is lower and the fit is snug throughout the length of the shoe. The mesh is a little bit stiffer than previous, which combined with the slight taper at the forefoot makes for a slightly short fit. This makes the shoe fit more like a shorter-distance racer, which it is. The toe box and forefoot are especially low volume without a ton of wiggler room. This transitions into a snug midfoot with a non-gusseted, thin tongue. Thanks to the security from the heel and the snug fit, I had no reason to tie down the laces and did not have to worry about the thin tongue. The heel also fits snug and does not have a heel counter. There are two pads of cushioning at the top of the heel collar on both sides that further locks the foot in. The similar "SlingLaunch" heel, which is really a large external overlay that starts at the midfoot and wraps up and around the top of the heel, continues to do a great job of securing the heel. I did not have any slippage in this upper and did not have to lace lock the heel.
While the upper continues to breath well, the inner mesh is still scratchy with several exposed stitches. I would highly encourage socks as I have had several hotspots along the top of my midfoot and toes. Overall, the fit is secure, lower volume and snug (but normal for a racing shoe).
PERFORMANCE
The Takumi Sen 10 is a 5k/10k race shoe that still has plenty of cushioning with 33mm under the heel and 27mm under the forefoot. The Lightstrike Pro provides a balanced feel between soft and firm like prior versions. The weight is still light but sees an increase from the prior version to 6.98 oz. It still feels nimble with a fairly responsive midsole.
Unlike traditional super shoes, there isn't as much bounce or stiffness. This shoe relies a little more on your own body, but the Energy Rods 2.0 still provides a snappy feel when running faster. The new rods feature an extended section into the lateral midfoot and feel well integrated into the sole. Prior versions felt as if the cushioning would bottom out and I could feel the rods but not in this one. There is an 6mm drop and that is exactly what it feels like. The heel transition is fairly smooth with some bounce and snappiness. The midfoot is a little stiff, particularly on the lateral side. If you are moving at faster speeds, it feels like there is a little push toward the big toe which feels nice to shove from. If you are moving at slower speeds, it feels like the it pushes you off the medial side of the midfoot. This transitions into an especially snappy midfoot that despite its stiffness still transitions smoothly.
Given the lighter weight and nimbleness, the Takumi Sen 10 works best for shorter workouts, faster intervals and shorter races from the mile to the 10k. While there is plenty of cushioning for these distances, I would want something with a more centered midfoot and a bit more propulsive over longer distances. Going all out and at faster speeds where you are really pushing your own body is where this shoe does best, rather than longer consistent efforts where you might want a little extra bounce. I found shorter tempo runs were fine, but often ended up wishing I had a bit more over a few longer efforts I used these for.
The outsole is durable with no noticeable wear after 25 miles of all hard efforts. The traction does great on road and track but I would not take these on dirt. Rocks quickly got stuck in the little midfoot window for the rods and I began to worry about punctures through the exposed Lightstrike Pro. Overall, this is still a solid shorter-distance road/track shoe for those who still want Lighstrike Pro and some midsole stiffness but without as high a stack height as the majority of super shoes out there.
STABILITY
The Adidas Takumi Sen 10 is a neutral racing shoe. There are no traditional methods of stability. There are no sidewalls and the medial midfoot is cut away/narrow with only the lateral side filled in. The new rod design (Energyrod 2.0) does have an extension/fill-in at the lateral midfoot, which creates extra stiffness there. This was immediately apparent to me and although similar to the Boston 12, was much more noticeable. I immediately felt a push toward the medial side of the midfoot.
Because of this, the Takumi Sen 10 features some medial guidance in the midfoot for those with lateral stability needs. This may be problematic for those with lateral guidance/medial stability needs at the midfoot. There is a small posterior lateral heel bevel, which does provide a nice transition at heel strike. There is also a small medial sidewall at the heel that I did not notice for the most part. For those still concerned after the massive posterior lateral heel bevel that threw people laterally in the Adios Pro 2, the Takumi Sen 10 does not feel like that at all. Outside of that, this is a neutral racing flat that will work best for most people over shorter distances.
Thoughts as a DPT: Lateral Stability in Footwear
By Matthew Klein
As someone who needs medial stability, I tend to focus heavily on medial stability methods in footwear. That does a disservice to those who need lateral stability, so rather than demonizing as I did in the Boston 12, it may be time to discuss who would benefit from lateral stability in shoes and how to identify footwear with it. Stability and guidance can come in many forms that we have been talking about for years. The more obvious ones recently come in the form of sidewalls, which most companies usually put on both the medial and lateral sides of the heel and/or midfoot of shoes (but not always). A lateral sidewall will provide lateral stability and medial guidance as it will resist motion going too far lateral and will facilitate motion toward the medial side of the shoe. As we have discussed with plates/rods, additional stiffness on the lateral side in the midsole will also facilitate motion medially as an individual's movement pathway through the shoe will generally pass through the path of least resistance. The lateral project of the Energy Rods in the midfoot of the Takumi Sen 10 provides this stiffness, which will provide some resistance to excessive lateral motion and facilitation of more medial midfoot. This may be challenging for those with medial stability needs, but is an interesting tool for those with lateral stability needs.
It has been far more common to see shoes with medial stability designs than lateral until now. Previously, a great deal of the medical and footwear community believed foot and ankle pronation was a major source of injuries. While that may be true for certain pathologies like Achilles tendon, posterior tibialis issues and a few others, it often does not influence others (Willems et al., 2021). The industry now has moved away from "correcting pronation" to more of a "centeredness" concept to help facilitate forward motion regardless of where the foot deviates. This included an understanding that while not as common a movement, some people do supinate a bit farther than they can control. Rather than making specific lateral stability shoes, the industry has been using guidance concepts on both the medial and lateral sides of the shoe with recent examples including the Kayano 30, Saucony Guide 17 and others. This idea of centeredness captures a larger variety of human movements than biasing a single direction, since the goal of a shoe should be to help facilitate forward motion and getting the foot/ankle back to the middle rather than excessive motion in one direction.
RECOMMENDATIONS
The Takumi Sen 10 is fairly similar to prior versions outside the new Energy Rod 2.0 design. It has been refined, but at the cost of some weight increase. Many people are still going to do fine buying the Takumi Sen 9 on sale, especially because based on the weight and design, that is the best version in recent years.
At this time, my recommendations for the Takumi Sen are going to be borderline useless because Adidas is probably already working on version 12. However, after this many versions, the debut of new foam in the Evo Pro 1, the Takumi Sen series needs another foam update. 6.9 oz / 198 g is still on the lighter side, but it is half an oz heavier than the previous version, the Vaporfly and the SC Pacer. It is also a similar weight to many other full stack height super shoes like the Alphafly 3, Endorphin Elite, and Metaspeed Sky+/Edge+. For years, Adidas shoes have been known to be heavier than competitors. However, newer shoes like the Supernova Rise and the Evo Pro 1 have shown that this company can do light while still maintaining a high level of cushioning and performance (and the Rise could be even lighter if they got rid of the posterior heel flare). I don't think Adidas can modify the geometry of the Takumi Sen series anymore without sacrificing the structural integrity of the shoe. The midfoot cut-out is already large enough and I don't think they can extend a central cut-out into the forefoot as the rods don't provide enough torsional rigidity to handle that. If they are going to stay with a similar stack height and design, a new foam is the only option for an upgrade. Adidas could reduce the stack height to greater differentiate the shoe from the Adios Pro 3 (is there going to be a 4?).
Overall, I can't criticize this shoe too much as it does do its job and its intended purpose well. The Takumi Sen 10 has a high stack height and nimbleness for its weight and definitely performs well over shorter distances. It has been consistent over the last 3 years, which may be a good thing for some people. However, if they are going to continue to charge $180 for this shoe, then they need to make sure it is worthy of that price in the current market. The other major competitors to this shoe are the Hoka Cielo Rd ($160) and the Streakfly ($160). The Streakfly is almost an oz lighter but doesn't have the snappiness that makes it feel faster (in fact it feels better at tempo and moderate efforts). The Cielo Rd is the major competitor given the Pebax midsole and stiff ride that makes it feel really snappy. It has almost the same stack height but feels firmer compared to the Takumi Sen 10 and bit faster over mile to 5k distances. This category is slowly being built up as some people realize that more moderate stack height racing shoes may work better for them. Adidas needs to stay competitive here if they are going to charge $20 more and I still think a major foam update is in order.
WHO THIS SHOE IS FOR
The Adidas Takumi Sen 10 is a shorter-distance racing shoe for 5k/10k races, interval workouts and lower mileage runs. Those who want a snug racing-style fit that is light and secure will enjoy the upper. The slightly short fit does break in but some may need to adjust their sizing. The ride is similar to prior versions except with the extra stiffness at the lateral midfoot and a slightly better integration of the rods with the foam. Those who want a nimble ride that isn't max stack height but still has plenty of foam underfoot will enjoy this shoe for faster efforts. The Takumi Sen series continues to fill an important role as a shorter-distance, nimble racer in an era of maximal stack height longer-distance racing shoes. It does gain some weight, so those who want the lightest version should look at the Takumi Sen 9 on sale.
GRADING
