Swiftwick - Aspire Two, Micro-Crew Compression Socks for Endurance Sports (Large, Black)

Just finished a half ironman in 90 degree weather in these, and they were fantastic. Usually I'll change socks between the bike and run, but these felt great and I wore them for both parts. No blisters, no weird seams to rub. They stayed up and didn't bunch inside the shoes. The compression is helpful for foot fatigue and swelling as well. Honestly, I didn't even think about my socks the whole time, which is great. Yes, they're expensive. I could get a 6 pack of cheap socks for less than one pair of these. But to me it's well worth it to not get blisters and for my feet to be cool and dry on long runs and rides.

They seem ok .but the sizeing is very tight. I got the large but they feel pretty tight . I have a size 10 fit .

Love these socks. Perfect fit for my men’s10. Not too tight on the piggies, but not bunching up either. Perfect thickness for my tastes. Wear them for everyday, even for dressier occasions with slacks since I buy the black color and the white logo is pretty low key. Also wear them for running - everyday training miles up to Ultra distance. Again, perfect thickness and fit for protection and blister prevention but tiny enough to be cool and stay smooth under shoes. Tend to last a long time, years even, but eventually the elastic properties wear out and they lose their perfect fit, ultimately getting a hole in the heel or toe.

Really good performance socks.

Like the fit and feel. Return buyer.
