Or is the performance they provide dictates the need? Only asking as I prefer minimalish shoes, 6mm drop or less but minimal cushion. I like to feel the road/trail. However know many, especially those trying to place in races have to go this route because the add benefits. Think these have the carbon sole that, through some science and energy efficiency, make each step "easier". Just curious coming from someone is balking at the new norm/style. Regardless, they cool and fast.
