Question: what size do I buy for a size 10 shoe?
Document: Have only used them once but it was a day of constant and heavy rain and they kept my boots and socks dry. They also keep your legs very warm. I'm a UK size 10 shoe and the fit is fine for me. Good product!
These are great gators, but the sizing is wrong. I was told I needed a large as I wear a size 9 women's shoe. They are way too big. A medium  would be good.
Seems to be well constructed. had no problems with them riding up. I used them while digging snow caves. Had no problem with them whatsoever. They stayed secure and tight and did not let any snow in. I bought the large gaiters which I used with my size 10.5 north face boots. They where tight but the size was right.
I purchased a pair of these for a backpacking class I was taking last winter and they worked wonderfully in the snow. They kept my legs dry and added a little extra warmth. Initially I got the wrong size. I ordered the XL since according to their website it would fit between 10-13 size I am a size 12 I thought that would work, well what they don't tell you is that you need to have calves the size of the Hulk to keep them up.
just a warning, dont buy from vitatronics. they will send you the wrong size. not a big deal until your counting on them coming in two days so you can go out with your friends and family on scheduled events. the medium seems to fit over my boot but at 3 sizes too small, it doesnt even go halfway up my shin, i think this product might be more reputable if it were the right size
This has included plowing through sidewalks that were not shoveled ( 10 inches of snow) to packed hard snow that I had to climb over to get to a path way.If I had any complaint at all, it would be that the top closure will never get tight enough. Even at it's tightest if I were to get into snow over my knee it would get down the top of the gaiter.
I've worn these a couple of times. I used them with the MOAB mid waterproof hiking shoes. These have durable construction and are also adjustable via a buckle on the bottom. I got the XL and I wear a US 11 for that hiking shoe and they were tight at first. I was worried they would not fit a larger gortex boot, but then I saw the adjustment which covers what appears to be a large range and I have no doubt they will fit on boots.
I tested these gaiters out a few days after I got them. I hiked about 5 miles in 10" deep snow on a recent elk hunt in the Colorado Rockies. When I got back to camp my pants were completely dry and everything still tight. I was surprised that these fit over my Rocky brand Blizzard Stalker boots( very bulky) while wearing thick pants AND insulated overalls. They were easy to put on and kept the snow out. I will use these as often as I can.
I'm a size 15 and these are perfect for me over hiking boots. Wish I would have bought a long time ago. So much better than side zip gators.
I purchased these for a snow trip; I was about ready to get on a snowmobile and pulled these out to fit over my size 13 Sorel boots. No go. Just way to small. If they have a XXL that's what I'd recommend for this size range. They appeared very well made. I returned for a refund and that went fine. The seller was reputable for the return.
