Used about 4 times. I feel like they run small (even with thin socks like in the picture *nike hiking thin black socks) I went and got me a bigger size. I am a trail runner and wear wool socks. Anywho. I think they would be amazing if you wear a 6. But the size is 6.5. Got them at the Nike outlet for $79.99. I just want to get $30 back. They super cute and they don’t slip on wet rocks. Feel free to ask.
