These invisible socks are well made and true to size, but they irritate me a bit because they have an unusually high proportion of polyester or nylon at the expense of cotton; This makes them quite smooth and thin when worn. They remind me of nylon socks. They actually grease the inside of my adidas, so I have to lace them tighter than I'd like to keep them from riding down my socks. Saucony maybe but I wouldn't buy them again because I prefer thicker, softer socks that I wear with pumps and you could be like me. I like cotton for socks (at least the high cotton content; of course you always have different fibers for elasticity and other properties) because it absorbs moisture and is also of course very soft and comfortable on the foot. Again, these are all fine except they feel like silk socks, which annoys me. I have to be picky!
