MTN Racer 3

TrailReleased 2023-08-09JP

MTN Racer 3 is a neutral trail shoe for technical racing, longer efforts, and hiking. Compared with its predecessor, it adds forefoot room and more cushioning, pairing an updated ZipFoam midsole with a responsive feel. Vibram Megagrip supports traction on wet, rocky terrain, while the gaiter-compatible upper, roomy toe box, and secure midfoot and heel help maintain confident footing on uneven trails.

Weight measurement and plate details
Weight note
Topo Athletic Japan's exact men's product page lists 286 g for men's M9 and 235 g for women's W7.
Plate note
The exact official JP men's page provides a complete construction description covering the updated ZipFoam midsole, Vibram Megagrip outsole, upper, and core specifications. Fleet Feet's exact men's page corroborates that construction without identifying a carbon structure, so carbon_plate remains false. The presence or absence of any non-carbon plate structure is not asserted.
