When it comes time to ditch the waders and hit your favorite high country trout stream, reach for the Patagonia Yulex Wading Socks with Gravel Guards. In order to make a more sustainable wading sock, Patagonia did away with traditional neoprene by opting for a combination of natural and synthetic rubbers. This also gives them a slightly thinner feel than neoprene, so they're more comfortable to hike and wade in than bulky neoprene booties and wading socks.
