In reply to Phil1919:
I've got a pair, wear them for my long runs ( 16+ ).
Only criticism in the past is that they are quite heavy, which is not that surprising when comparing them to "normal" shoes. really excited however to try the new Hoka Clifton which is just out in the US, should be here in a month or so, which is just 220g - that's the same as my Adidas Adios Boost race shoe ! This sounds like my marathon shoe of the future !
