Despite a lot of riders liking this shoe, personally I found the mid-sole and insole design poor. On the outsole you have the grip which seems good. But, but then you only have a thin plastic midsole then the insole/footbed. So you are standing on thin plastic covered by a thin insole insert. I always wear and run in minimalistic shoes and even go barefoot alot but this shoe just seems odd. Maybe it is because I have high arches, I don't know as most people seem to like them. They also have a lot of heel lift, like I've found with all Shimano shoes. Returning them. Will stick with the Five Ten Impacts I have for how.
