Only worn a couple times; the shoes are still in like-new condition (see pictures). Size didn't fit and I missed the return window! Men's size 10.5 (Regular Width). From HOKA website: The lovechild of Mach 4 and Mach Supersonic, this lively pavement pounder is built for performance and ready to race. Sporting a stripped back creel mesh upper and lay-flat tongue, the new Mach 5 delivers a snappier ride with PROFLY’s stacked midsole setup, offering a lightweight, responsive foam directly underfoot and rubberized EVA below.
