The soles are perfectly affixed to the canvas uppers, with no gaps showing. This sweater is so much nicer than i really expected . There is a lot of drag and they dont spin well. I finally had the opportunity to put these on and go for a run. I recharged it again, and the right headphone kept disconnecting. Like other reviewers, I find the buckle very difficult to fasten because the buckles prong has a very sloppy fit on its axle. Looking for a rack for a tight spot? This one is perfect. Robust. Top straps were stretched out. My old Nike sandals that are comparable to these as far as price and design were comfortable all day long and offered a lot more support.
