I wear a size 11-12 so I bought a Large, I received them fairly quickly, tried them on and the straps fall off my shoulders, they will not tighten anymore and the legs are fairly long and very bulky - I looked HUGE in them. Originally bought for light snow play and sledding. I have to return them. The description size buy one size bigger than you wear - so not the case with these. Not sure where they got that from.
