good quality. Smooth inside feels comfortable barefoot. The sole offers good grip and cushioning and is very light. The size is a little tight. Men's size 8 is listed as a 40.5 but fits like a 39/small 40. I wear 40 in Sketchers and Birks and they fit perfectly in length and width (woman's foot). Being water shoes, the hybrid fabric and neoprene upper that hugs your foot is fine, but it's just a hair shorter than I'm comfortable wearing. In the end I settled on a 9. The style and overall feel make you want to risk it.
