Comfortable, warm, versatile, sturdy. It is very handy to have in my toolbox as I move around the house hanging things. I purchased the black with white soles, size thirteen. Sound quality ?? You also still have Noise in the background so ??Not worth the money! Then I washed them with like colors (brown, pink, reds). They run about a half size small so make sure to adjust for that when you order. Its just not built for this. Then change was easy so that was nice. Now granted its not an essential piece for the flip-flops, yet it is something that detracts from the aesthetic. These are super soft.
