I just got these in the mail today and I haven't been able to take them off! SO comfortable! They are definitely a "barefoot" shoe: very form fitting to the foot and lightweight soles. I wear a 7.5 and ordered an 8 after reading the reviews. The 8 is perfect with bare feet or thinner socks but I would definitely go up a full size if you want to wear these with thick socks. These DO RUN SMALL. These seem like great quality shoes, the stitching looks beautiful and I love that the bottom inside liner attached by velcro so you can take it out and wash it. I will be wearing Jambu from now on!
