They are like walking on clouds, they are made really well, you can get them wet because although they look like an expensive leather sandal they are synthetic. It did come without instructions, but customer service immediately e-mailed instructions to me. I jumped on a sale but honestly am not really happy with these. Along with the startup and other beeps are loud and annoying. I am really rooting for these shoes, and so far give them 5 stars. I found a video on YouTube that helped. These straps were very oddly fitting very large or a very small at the same time. The blue one fits my son perfectly, with room to grow, but the white ones fit horribly. The comfy fit, and quality is why I stick with these. I just got these boots a few weeks ago, but have already hiked/walked about 50 miles in them, including through crusty New England snow, ice-covered streams and rocks, and in the rain.
