The great thing about our niche corner of fashion, is that no matter how simple something may seem, there is often years of R & D and an insane amount of care and knowledge bound up in the final product. You might think something like an indigo-dyed boot sock might be simple, but not when Hudson’s Hill is working their magic.

The Warp Ragg Sock from Hudson’s Hill uses a dye technique developed with funding from Wal-Mart‘s Made in USA initiative. The pad foam dye technique is extremely low waste and Hudson’s Hill was fortunate enough to snag a few boxes of the low-waste yarn.

Plied together and then knit on double-cylinder knitting machines, all in North Carolina, the socks come in a 6-ply midweight and a 7-ply heavyweight. As this yarn would have otherwise been used for warp threads in denim, they’re an appropriate choice for the denim-lovers among us.

With just 100 pairs were made per weight,  you’ll want to move fast to get your own heavy-duty boot socks, with just as much fade potential as your favorite jeans.

Available for $32 at Hudson’s Hill
