I LOVE these shoes! I have been wearing Salomon Speedcross  for the last few years. I wear them to the gym, I wear them hiking, I have worn them for adventure racing. Next up: I am trying to get into trail running and they will be my go to for that as well - the aggressive tread is perfect for trails. I usually wear a 9.5 in Asics* but I am able to size down to a 9 in these. They are comfortable straight out of the box. I have never had any issues with blistering or the shoes rubbing my feet. I have a very high arch and I feel supported in these. I love the lacing system because it enables you to get a custom fit and I love that the laces can "disappear" under the tongue if you want them to. I have an older pair of Speedcross 3's and this is my second pair of the 4's. I love the bold colors and styling of these shoes. If they continue to be this well made I will be wearing Salomons for life. *Actually gave up my Asics once I found these - for my foot type, these are the clear winner!
