When I saw these on sale, I bought 2 extra pairs in case they are being discontinued. These are a minimal ultra light solution to keeping stuff out of your boots, and my go to trail gaiter unless there is deep snow or boot sucking deep mud. They are water resistant enough for light moisture, which I found out when trying to improvise a pre filter for my drinking water, and the water bounced right off. On very wet days and slushy snow excursions I've kept them on underneath my regular gaiters and they have helped there too. My only regret is the choice in colour, as for hot weather the black isn't the greatest and the blue can get guys a bit of teasing (not that it's stopped me). The velcro works decently on my trailrunners, and I don't even bother with it for my hiking boots. I wear size 13 with skinny ankles and the L/XL work great.
