I have quite narrow feet with high arches and these sandals fit me perfect. They run very much true to size (surprise as I've gotten several shoes recently that don't) and the sole width is average. The laces are not adjustable even though they look like they are; you could tighten them, but then the leather part on the top of the sandal deforms such that it's uncomfortable. It's the first pair of open sandals that I've bought online and I'm very glad I took the risk, the reviews helped a lot!
