I read from the TW review that the fit/arch is comparable for both shoes. Can the same be said about how narrow it is? I recently found out the my feet could barely fit in the Genius 2 at half a size up. Would my feet fit the Adizero Feathers at half a size up too? How about the length? I noticed the Genius 2's half a size up were at the same length as the Barricade 6. Same as in the feathers?
