had a problem with the top of one of my toes on a foot - blister/hot spot in the shoe... after awhile, though, the shoe brokeIN and is good2go... very comfy to jog in (treadmill at the gym), and work out in (weight lifting), and walking around town (city walking)... bought a 2nd pair since price is right, and am thinking of buying 2 more pairs... had Adidas before and REALLY liked them, but their price is no longer in a sweet spot, so turned to ASICS...
