You may find that a pair of your compression socks feels tighter than the others, even in the same size. This is normal! Different fabrics will feel differently on your legs. For example, nylon socks may feel more compressive due to the denser weave (400 needle-count) - however, they offer the same compression that you'd get from the same compression level in a cotton sock. Customers often remark that our cotton socks feel the most stretchy & easy to put on.  Our products are regularly tested and quality-checked to ensure they fall within the listed compression range and correct size measurements - so you can be assured that the socks you're wearing are delivering all the benefits of graduated compression. It's important to note that some of our more complex designs do have stitching on the inside that some say makes the sock feel tighter or harder to put on. This is the nature of a sock that has the design woven into the fabric, rather than printed on the surface. If you are concerned about fit, we do recommend starting with our simpler designs to begin getting your legs used to the feeling of wearing compression socks.
