Best shoes I’ve ever worn! Beyond comfortable for walking, exercising, whatever! My toes can move inside, not so tight…highly recommend these shoes!Bought for gym shoes. I wear an 8 in xero sandals so I went up to 8.5 in these. I think they fit great, a little loose in toe box and I like that. I haven’t had them long enough to give a 5 star, yet.These are my favorite shoes in the entire world!! We went on a 2 week trip to Philadelphia, Hershey, Washington DC and other sites in VA and PA. I had just ordered these shoes and wore them every day all day! I could tell my muscles in my upper legs/hips were more engaged than when I wear my normal shoes. I was less fatigued and had less sore feet and muscles from all the walking. I haven't done much running in them, so I can't speak to that, but as for a lot of walking on paved and unpaved surfaces, these are the greatest. I will be buying them again!!!! Note to company, please add some softer, muted color choices! I'd love a soft grey color.In terms of size: usually I wear a 7 in athletic shoes, but the 6.5 fits me perfectly.I bought this shoe directly from Xero. After a week the insole came out and wouldn't stay in. I contacted customer service and after a month of back and forth, they told me to use double-sided tape. Terrible customer service and low-quality shoes. I would not recommend them.?
