I am actually enjoying the simple high mileage shoe, Reebok One Cushion. The last is built with a pretty good curve for high arches and it has a tough carbon sole with good traction all while being a decent lightweight. I did size down 1/2 size from Brooks.
Obviously Tyler Pennell runs for Zap/Reebok with my use of the One Cushion I could not find any info on his racing flats is this a case of just making a custom/limited pair for Zap because they have the focus on the Crossfit?
