Good and comfortable toe socks
Size: 10-12, Color: Black 5 Pairs
First time wearing toe socks. I bought them to help prevent athlete's foot between the toes, which I'm prone to getting. Being a guy, I did have some reservations because I thought they'd look silly or whatever but I went ahead and bought these since they're going inside shoes anyway. I'm so glad I did! My only complaint is that the length of the toes are a bit short. In shoes I wear a men's 11 and I ordered 10-12 in these socks. The overall length is perfect but the toes are a bit too short and won't go all the way back to my webbing in the 1st and 2nd interspaces. The other toes and interspaces are fine. It's a minor complaint and not enough to remove a star. Overall I'm very satisfied with the product. I've suffered from Morton's Neuroma in both feet and various interspaces all of my life. I think I've finally found the solution. I've been walking 4.4 miles a day for over a month now. Something I've never been able to do. I wear these ZAKASA toe socks, along with the Dr. Wolf orthotics which have good arch support and a metatarsal arch just behind the metatarsal heads. I also wear the Bronax shoes which have a wide forefoot to let the toes spread out. The combination of the shoes, socks, and orthotics has worked wonders on my feet! No athlete's foot either! I highly recommend these ZAKASA toe socks. I've bought two 5 packs already. No regrets!

Great quality and price per pair
Size: 10-12, Color: White 5 Pairs
Had these about 6 weeks now and am very pleased with how they've held up so far. I've gone through 2 other brands before this and will be sticking with them as long as they continue to hold up. Seams are still good, toe hasn't worn through at the toenail, no visible fading/wear on the pads of the feet. They are still annoying to straighten out after washing like all other toed socks, but the fit has held up and elastic is still snug and comfortable after daily wear (I did buy 2 packages, so they do get rotation before being worn)

Good for wearing with Vibram Fivefinger shoes
Size: 8-10, Color: Black 5 Pairs
They are good, comfy socks that fit well on a size 43 eu (9.5-10 US) foot in medium. Be aware that these are the same socks that you get when you order Caidenieu toe socks and dozens of other listings as well. So just buy the cheapest ones you can get. They come in the same bag with the same cards and everything. I wear them with my vibram fivefinger shoes very comfortably.

Great socks but overly snug
Size: 13-15, Color: Black 5 Pairs
Socks fit great. Very comfortable. The elastic around the ankles gets tight and uncomfortable as the day goes on though. Durable after many washes and they do not shrink. Colors don’t fade. They keep the toes warm and separated, which provides some bunion pain relief.
