These are the closest thing to a Yzy slide in the slides category, imo. They are on the heavier side. I’ve also noticed that with the adislide sandals, too. Fit is wonky on these slides. Your best bet is to try it in store. I was able to try out at my nearest sporting goods store store. For most slides, the adissages, adilettes, and adislides, I’m a size 9, but the purechill slides, I had to size down. I’m a size 9.5 in most bball sneakers. It’s a tight fit, but it’s EVA foam can mold to your foot. Comfort is subjective. I think they’re cushiony enough. Not overly plush like the cloudfoam comfort slides.
