I’m a size 10.5 and bought a size 11, based on reviewer comments about these slippers running small. It was a good move — they’re still a bit snug, but I’m pleased with how quickly they’re breaking in and adapting to the shape of my feet. The “outdoor” versatility means a firm sole, so while they’re comfy slippers. they may not be the best choice for those seeking ultra-lush comfort. The low heel counter takes some getting used to, as your heel can slip out and then step on it. Otherwise, the materials are high-quality and the shoes are well-constructed. I got gray, and they look great.
