Wouldn't recommend but I'll make use of them

I would not classify these as lightweight- I also had not read closely enough to realize these were seconds. Mine came with some holes already in the sock.

Rock-Solid Socks for Every Adventure I've had these REI COOLMAX EcoMade Lightweight Hiking Crew Socks for 4 years—zero holes, zero issues. They’ve survived countless hikes, winter wear, and wash cycles like champs. Comfortable, durable, and versatile. Highly recommend for trails, travel, or just staying cozy in boots!

My teenage son practically lives in cowboy boots and I’ve been trying to find socks that breathe better. I ordered 4 pairs and he loves them.
