They fit my plus size, wide feet--for the most part.  The top strap is a little tight but I'm planning on heating it up and stretching it.  They have been comfortable the few hours I've worn them.  I found they are not so good when wet as it caused my foot to slide forward which made me feel like I was falling so I had to carefully walk until they dried.  Update:  I took them to Disney World/Florida with me as the shoes to wear to and from the car as a comfort thing.  Unfortunately they did not do well being left in the heat of a closed car in August and they shrank--at least a size in length.  Now my toes hang over the front, the bands are way too tight across the top of my feet and the shoes are useless to me.
