These are great shoes that are worth more sold. I used the boards for the running of the trail and go skiing. For running on tar are comfortable but are not intended for her, for trail no worries they are lightweight and have a very good grip. For skiing I could test the Gore-tex is pretty amazing snow does not stick to shoes and do not wet, I had a little cold feet because the cold passes but at no time I ' got his feet wet it's great, I guess it must be the same for the trail in the mud (not tested). In conclusion it is really good trail shoes, light, with good grip is very comfortable (slipper effect) and a Gore-tex true effect.
