Or is it just me? I seem to get no joy out of that shoe, every stride feels like a chore, except the first km. The cushion seems to sink instead of providing me max energy return, making it very uncomfortable for quicker push offs. What am i missing here? should i learn to run like an ostrich first before wearing it....Also i have a strong feeling this shoe will lead to side knee injuries if you wear everyday... is adios pro any different, should i try that? Thank you ladies and gentleman
