The all new Mountain Racer features a 30mm x 25mm stack height. Topo’s proprietary Vibram® Megagrip outsole

design delivers optimal traction on any surface. Slightly firmer than the Ultraventure, the 3-piece injected EVA midsole

is performance tuned for trail racing and speed-hiking. A lightweight rip-stop mesh upper with printed overlays offers

a secure fit, while medial and lateral drainage ports enhance water release and quick drying. A 5mm anti-microbial

Ortholite® footbed resists compression set and odor.
