First time researching and ordering "Foot-less" compression socks, to find some vendors I can go to again, in the future. The quality of the NEWZILL sock is excellent. But I bought the wrong size, or their algorithm for sizes is different from other vendors. (A "large" with 2 other suppliers fits good; but the "large" with Newzill is just too big).I'll contact NZ and request an Exchange.Got the correct size, and LOVE how they go on/off & how they feel. Will buy more.
