New to me ankle height athletic socks
Yes , I recommend this product
First time with this sock style and brand. Bought them to wear with bike shoes for gravel cycling. So far, so good, but they’re still new. Fit well in the shoe with the right amount of Cushing on the sole with a lighter weight upper which is a great feature. They seemed to keep their size after a wash and dry, but I can’t really comment on durability yet. If they hold up, I’ll be buying more of them as I also ride indoors over the winter months.

Slightly padded foot, nice height for ankle boots
Yes , I recommend this product
This sock fits comfortably snug, with slight padding in foot. Did not bunch or ride down on boots after full day of hiking. Kept feet dry and comfortable.

LightWt Ankle Sockd
Yes , I recommend this product
This is my all-time favorite dress, hiking, landscaping, and street exercise sock. As I am on a fixed income, I am able to buy this quality feel & produced sock in "twosies" each month until I reach a sufficient number of pairs. Second REI Co-Op aspect about this item? There is a collection bin for gently used socks that cut off the circulation to my legs and feet which a much younger Rei member could use. Smart!
