Drew Rwrote a review of Adidas Adizero Boston 6 Running Shoe - Men's on April 4, 2017
Familiarity: I gave it as a gift but have feedback to share
I liked my pair so much I bought a pair for my running buddy as a gift since he was in need of new shoes. He likes his as much as I like mine.
He had the same experience I did in that they fit great right out of the box, did not require any break in and have not given him any blisters or hot spots. In his previous shoes he was getting a blister between his pinky and next toe, no issues with that in these.
He also found them to run about a half size small, his Nike's were a 10 and he went up to a 10.5 in these and they fit great and make for happy feet and running.
