I attached 3 photos for others to use. I am 511 and I weigh approximately 170 pounds, with a size 10.5 shoe (U.S.). I ordered the large. As you can see from the photos, the large is almost too big although I perhaps would be afraid to try the medium. The legs are pretty bulky. They seem comfortable. The stockingfeet are somewhat loose. Not sure how they are supposed to fit, but someone else may benefit from my photos and this information. I will modify my review once I have used these in mountain lakes, etc.
