GULL MEW Fins Size: MS Color: White (Cream) These are old, but there are no critical flaws, so they are usable. I used them for snorkeling, etc., during the summer until last year, but I am selling them because I bought new ones. For reference, my actual foot size is 25.5 cm, and I wear sneakers (VANS and All-Stars) in sizes 26.5-27 cm, but I was able to wear these fins without boots.
