RUNNING SHOE SUMMARY
The Topo MTN Racer 3 is a moderate to high stack height trail performance/racing shoe for those who want an anatomic fit and a snappy ride. A smooth upper sits up top with a snug heel and a wider forefoot providing a secure but comfortable fit. A new higher stack height midsole with a new Zipfoam formula provides a slightly soft but responsive ride. The medial post feeling in the midfoot continues, providing rare mild stability on the trail for those who need it. A great option for longer trail races and technical terrain, the Topo MTN Racer 3 returns ready for whatever pace you want.

FIT
(To learn how a shoe should fit, check out our full podcast on fit by Matt Klein.)
The Topo MTN Racer 3 fits me true to size if slightly short. In classic Topo form, the toebox is anatomic, rounded and wider. The toe guard is large and makes the shoe feel slightly short. This has not been an issue for me even over longer runs, although I do notice it from time to time. The midfoot fits slightly snug with a strongly gusseted and moderately thick tongue. I have not had to lace lock or tighten the laces at all. The heel also fits snug and hugs the foot along with the midfoot. This creates a highly secure fit that makes it easy to change directions or pivot without issue on trail. There is a moderately stiff heel counter in the rearfoot. I did not notice it because there is a large amount of heel collar cushioning and padding between the counter and the heel. Those sensitive to counters should be fine until the padding wears out. The inner aspect of the upper is quite comfortable with the exception of the toe guard. For that reason, I would suggest at least thin socks when wearing this shoe.

PERFORMANCE
The Topo MTN Racer 3 is a moderate to higher stack height, mildly soft and responsive trail shoe for uptempo efforts. The midsole comes in at a higher stack height than the previous version. It is still not towering but provides plenty of underfoot protection. The revised Zipfoam midsole is slightly soft with a snappy feel that allows quick paces changes. The weight is lighter than previous and the MTN Racer 3 also runs lighter than its listed 9.8 oz (men's size 9). There is a 5mm heel drop and that is exactly how it feels. The large posterior lateral bevel does provide a smooth heel transition regardless of whether you are on road or trail. This transitions into a slightly stiff midfoot thanks to the midfoot post feeling. The forefoot features a large rocker and is moderately stiff. These combine to make a quick and slightly snappy toe-off.
While the Topo MTN Racer 3 certainly feels good at easy paces, it comes most alive at uptempo efforts. I have used this shoe for a trail tempo and fartlek. Combined with the solid grip and nimble feel, it is a great off-road shoe for picking up the pace. The deep lugs and Vibram outsole are both durable and gripping. I have had no issue taking this through wet mud, soft surfaces, firmer dirt or even road. Despite 30 miles of use, I have no wear on the outsole (despite some of those miles being on road). While now not the lightest or most responsive shoe in the trail market, it makes up for it with a continued nimble feeling that makes quick footwork easy on a variety of surfaces.
STABILITY
The Topo MTN Racer 3 is a mild stability trail shoe. Despite not being listed as such, there is a clear medial post feeling under the arch, similar to the prior versions. This is not as noticeable walking but becomes apparent quickly while running. Those sensitive to medial posts may not do well in this shoe but those who want them will feel right at home. There are no major sidewalls outside of a small one on the lateral midfoot. I have not felt this but do feel centered and secure in this shoe (which also might be due to the snug heel). There is some mild heel flare that does not get in the way at all thanks to the larger posterior slightly lateral heel bevel. The midfoot does narrow a bit compared to the rest of the shoe but not enough to make it unstable. The forefoot sole is quite wide and combined with the mild stiffeness and solid forefoot rocker creates an easy transition forward. There is moderate torsional rigidity, which combined with the medial post feeling in the midfoot creates a rare mild stability trail shoe for those who need some support in the midfoot.

RECOMMENDATIONS
While I continue to enjoy the Topo MTN Racer 3 as one of my favorite trail shoes, I was a little disappointed in this update. While the stack height has increased, I expected more from the midsole for a shoe labeled as "racer." At this time, several trail shoes run the same weight or lighter than this. The Salomon Genesis, Altra Timp 5 and a few others sit here, so I would love to see the weight drop quite a bit. This could be achieved by using a PEBAX midsole similar to the Cyclone 2 and other shoes coming in the Topo line up. The would probably require a rock plate or plate of some kind due to the midsole compression. However, given that the "racers" of the trail are also using PEBAX, including the Nike Ultrafly, Saucony Endorphin Edge/Rift, Altra Mont Blanc Carbon and many others soon to enter the market, it is time for Topo to take their trail racer to the next level. Just don't lose the medial post feeling.
WHO IS THIS SHOE FOR?
The Topo MTN Racer 3 is for those who want an anatomic toe box with mild medial midfoot stability in a lighter package with the versatility to go the distance or pick up the pace. Given that I prefer performance shoes/lightweight trainers, this is a go to trail shoe for me. While not listed as a stability shoe, it certainly feels like it has a mild post, making it one of the rare mild stability trail shoes. I encourage Topo to keep this shoe as is except for a midsole update as it is incredibly rare to have a mild stability shoe with an anatomic toe box. The durability and uniqueness justifies the cost enough that I bought a pair myself! So Topo... be careful with version 4!
