“These are definitely waterproof. I don't like the constriction/lack of stretch in the socks. I can deal with tight toes over wet feet. The customer service here is superior as well.”
“I like that these have wool for warmth. I wear them running in Minnesota winters. I can wear my summer running shoes with these socks and my feet stay dry in sloppy conditions, such as slushy snow, and deep snow. The reason I did not give 5 stars is because they are billed as "ultra thin" and they are not thinner than competitor's waterproof socks. If your running shoes are tight, these may not fit inside.”
“They are stiff and tight at first wearing but soften up over time. I finally had a chance to ride with them in the rain and I can say that my feet never got wet. I'd love to try them hiking through a stream but haven't had a chance yet. So far pretty good. I got them for cycling in the rain.”
“It is just incredible how these socks work. I can step into 4" of water and my feet stay dry! These socks are much easier to put on than the originals which are tighter and thicker. I like that these are thinner and can be worn with a wider variety of shoes/boots.”
