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!
