Customer Reviews

Comments: Just picked these up from an upcoming half-marathon I have. Been a long time since I've worn a pair of Nike racing shoes. I agree they run 1/2 size long. Nice fitting upper, too. Just enough underfoot, I feel, for race day with an offset that promotes efficient landings. Looking forward to using these soon.
