I am normally an 8.5 in Brooks, and the 8.5 in this style fit really well and there was plenty of room in the toe box. In regular shoes, I am between a 7.5 and 8, but always go up at least half a size for my workout/active shoes. The cushioning on these is fantastic and they are very sturdy. I am a nurse, so I am on my feet 12+ hours a day, my feet still ache at the end of the day, but less when wearing these. No shoes are ever going to make my feet not hurt with all the standing and walking I do, I have accepted that. I have to say out of the Adrenaline (I use mainly for running) and Launch, these are my favorite to work in as the cushion is a lot softer and bouncier.
