I love these shoes. My feet can breathe but I can do some serious outdooe activities in these. They fit perfect.  I always wear a women's 10 Wide and I ordered the 10 and they fit beautifully. I love that you don't have to tie them or wear socks.  These will probably be my every day shoes... from hiking to deep sea fishing to going to the grocery store. I might even have to order these in more colors for the phenomenal price.
