I got my Pegasus 38 true to size because of a lapse in judgement instead of the half to a full-size up for trainers. I understand it's summer times and I mainly run on concrete that is really hot and my shoes will get warm but my right shoe is burning the sh*t out of the balm of my foot. It feels like the airbag is pumped way more than the one in the left shoe and it almost made my right foot go numb with how hot it was. Now I think this is due to size because my left foot is almost a half size smaller than my right foot. I was wondering if anyone had any input on this from their own experience or from intuition? I would hate to retire the shoes at only 150 miles but the burning is really really bad and I've had to stop my runs a couple of times and it makes me feel even worse because my left foot feels almost perfectly in the shoe and there's no burning.
