I find these shoes at this price really great! Though he fall (in my opinion) a little bigger - but that's still under. Wider feet will find in it lots of space! Otherwise, you should order one size smaller might prefer. Usually one a shoe attracts so yes even without socks. How does he do so when running, remains to be seen. During the test run in the house, it has definitely very convenient felt - as neoprene. And airy, the shoe is also, which is of course great for the summer. There are of me so nothing to complain about - therefore 5 Stars.
