I have been looking for women's no-show socks for awhile now, and all the ones I've tried are either really really thin material that always ends up rolling down the back of my heel and either causing blisters from rubbing on my skin, or they end up rolling down my hhel completely until their a bunched up mess in the arch of my foot and the only part still on my foot is at the toe. I've been looking for lightweight, (not super thin) no-show socks that aren't sewn with a seam that rubs the back of my ankle raw no matter how much I try to avoid it. I was beyond happy when I finally found WISVOOO 3-6 Pairs No Show Socks Women Non Slip Thin Liner Socks for Flats Boat Cotton Invisible Hidden Socks - 6 pairs (Black x2 + Beige x2 + Grey x2), Women Shoe Size 5-8.5. Not only are the the perfect thickness, breathable, and comfortable on my feet, but the best part is the seam is wider and sewn flat so they don't rub on the back of my heel all day. My absolute favorite feature though, is the inside the heel of each sock, are these little silicone rubbery-like grippies like I've seen around the top of thigh highs, that really do grip the sock to your skin and actually are very effective at preventing them from moving at all. I walk to town and back a lot, which is about 3.5 miles. It's always hot here in Arizona, and rarely do I wear long pants when walking that far. I hate the way ankle socks look with sneakers, I feel like I'm late for a tennis match. No-show are the only way to go, but there is nothing more agrivating than getting into my groove on a 3 mile walk, and having to stop every 3 minutes to adjust my sock or reach into my show to pull the back half out and put it back on my foot again. I can't tell you how many pairs of socks I've just taken off and thrown away because they were so frustrating. Not these socks! These came with 6 pairs in 3 different colors, and I honestly haven't found a pair of socks that I like better. They don't show, they STAY PUT, the seam never rubs my ankle raw, and they provide cushion while still being breathable and lightweight. Love them!
