I discovered Cobian flip flops a few years ago and had the Nevada model (very similar to the Nias) in 4 colors. I live in Texas where you can wear flip flops everywhere and it's summer 8-9months a year. I wore those shoes every day for several years and they held up. The surface took a beating, but the integrity of the shoe is still intact. I just received my Nias and they feel like the others and I am confident they will wear and survive as well.
