Lightweight and nice looking on the feet. I wear a size 8.5 US and I purchased these in a size 9 US. I wore no show quick drying socks and avoided the problem of the seam irritating to top of my feet and the sand irritating the bottom of my feet. I wore these all day and they were comfortable. I wish that they made a walking shoe with intact soles out of this material. They were great for traveling. Easy to pack.
