  • I wear a size 9.5 casual shoe and I normally wear a 10 in running shoes (for a larger toe box). I ordered the 10 Chaco z2 and they fit...a 9.5 would be perfect as the 10 is a little on the large side but they do fit and the 9 would definitely be too small. I would order the 11.

  • I have a size 11 foot and I ordered a size 12, I do this every time. I order sneakers or hiking boots a size bigger, because I want a little extra room. With these they are so adjustable ordering a little bigger is not an issue. The full size up for me works great. A tip when you put these on. Pull on the cross toe strap and the diagonal strap across the foot, then your foot slides in nicely. It took a bit for me to figure this out. In the picture these cross straps go in the same direction..

  • My shoe size is 11.5 and I got the size 12 and they are too big. They still function and are comfortable but I wish I had gone down.

  • I suggest you figure out what your size is in Euro....(mine is 40, and I wear a women's 9...the men's 8 fit perfectly) and cross reference that to the men's sizes. My issue is foot width...so that is why I ordered the men's size. I understand that the women's run narrow. They also give a sole length measurement. All euro sizes are pretty consistent as I have found. Now, if you have a pair of shoes that you like and fit you well, measure the length of the sole and match it to the same measure as given in the size charts. Between those two, you should find out the right size for you.
