Hello! I love the swiftwick socks. I prefer the one, not the zero . I tried the zero tab and it was ok but i like the one better. The only problem is the colors. In the past i could get pink, orange, aqua, and lime green and now those colors seem to only be for zero. If you want one you get grey or navy just not very feminine. I have been getting swiftwick for 10 years. My husband and i started using them because he is an amputee and he first started using them on his limb then we started using your other products and were hooked. I gave your socks to 5 people for Christmas presents, but just men. Just wish the " ones " were more colorful but love the fit and how you cant feel the seams!!!! Lin
