In my time buying from Amazon, this is the first time they ever sent the wrong size. I got the boots, tried  them on. they felt just a bit roomy. I walked around a little bit. They performed well on the hard packed snow, not so well on glare ice. They seemed a bit light for winter use. After the initial test, I took them off  and saw they were a size 13. I ordered a 12. Had they been a size 12, I would have rated then a 3, but definitely not a five, because of the poor traction on ice. I returned them and ordered a pair of Teva Forages, which have the same issues with glare ice, but are warmer..
