"These shoes have made it possible for me to run again. I have to go up a whole size to make them comfortable though. They run pretty small. I have narrow feet with very high arches and these shoes fit my feet like custom made shoes. I will miss the color combo of my old ones, (grey, blue and tangerine) but the purple is nice this season too. They are great for trail running, and great for road running. They are slightly slippery on any other surface if it's wet, though. They are nice and light and they breathe really well. Try them on, get the right size. If they are the shoe for you, you'll know if immediately and never want to wear another pair."
