The size is a bit big but not bad. Thin summer socks slip and thick winter socks fit well. This is the second pair I've bought. The sole of the first pair eventually wears out in 4 years. The top is still in very good condition. You breathe really well. The outsole isn't slippery but grips wet tiles better than most running shoes. Overall, this is the most comfortable closed-toe shoe I've ever had. I would buy them again.
