I was disappointed that there was no way to make the cross-straps smaller--they are supposed to be adjustable, but the way the buckle and velcro are sewn, it is impossible to adjust them for a thinner foot. On this sandal it can be adjusted for bigger, but not smaller. I was very sad to send these back because they would have been very comfortable. I have a similar Naot sandal from 6-7 years ago that is still very comfortable, and I wanted a replacement. This foot-bed is smaller that my previous Naot in size 40. It seems a bit shorter. If the straps were more adjustable over the instep and forefoot, I would have loved these sandals. My old Naot is still the most comfortable sandal I've ever worn. The seller had my order here quickly and gave very good service. I got my refund very promptly. Sorry it did not work out.
