I normally wear a 7.5 US or 38 EUR. My foot width is medium or a little on the wide side at the toe area. I used the measurement chart and compared with a sandal I have. Women's 8 fit perfectly. I did adjust the back and side clips to fit to my foot. The release on the other side makes them easy to put on and take off. I'm with another reviewer in that I love to go barefoot but now prefer this sandal. The foot bed is firm, so no fighting with foam for proper balance. Very stable. No irritation from toe strap or any other strap for that matter. I got the slate blue and the color is a darker blue than the picture, which is what I was hoping for. Converse flip flops were another favorite (not for hiking) but they don't make them anymore. The flip sound can be annoying. These are more comfortable and secure and I can be stealth with no sound. Plan to buy a second pair before there's some design change. They're perfect as is.

I have waited over a year to order these sandals because my previous ones still had a little bit more life left in them. I was very excited when these arrived and wore them immediately the next day. Adjusting the straps to get the correct fit was super easy and they were comfortable on my feet immediately, which wasn't the case with my previous sandal brand because I had to build up calluses in certain areas. I am very happy with my purchase and will definitely be loyal to these sandals moving forward!
