I've worn the adidas adios boost for the past 3 years. It's my only shoe for all training and racing. However, I've been training for my 2nd full marathon and my feet are starting to hurt/ache on the long runs. I'm really curious what other runners might suggest as a more cushioned alternative to the adios. Plan on keeping it for speedwork, but it's killing me on anything over 13 miles. Thank you in advance!
