Fox River Bilbao Crew Socks

Color: Gray Heather

Fox River's Bilbao Merino wool crew sock is a perfect (and never scratchy) sock for anyone seeking a dependable hiking sock. The high Merino wool content of the Bilbao means good value and a perpetually dry foot (one of the most important qualities in any good athletic sock).

The Bilbao's fully cushioned sole will help you stay your course on the trail all day. Medium weight sock frame will keep you warmer, and added arch support helps with extended comfort. Bilbao's low-profile toe seam won't irritate tootsies. Like all Fox River products, the Bilbao hiking crew sock is proudly made at their mill in Iowa.

sad to lose the Bilboa model

It's not anything you could do about it -- apparently Fox River has discontinued the Bilboa sock. My favorite sock for eons!

Not What I Hoped

I bought these socks to compare to my Darn Tough and Wigwams. Positives:- They are well constructed, warm, and comfortable. - At full price, cheaper than others. Negatives:- I've worn them a few times and they are starting to get a lot of pilling. - These start to get a little funky when worn during the day more than 1 day in a row. - They don't hold your calves as tight as others. I'd compare these in feel and appearance to green military socks. For the money, I'd pass on these if you can get the other brands on sale for the same or cheaper.
