I waffled for so long on getting some darn tough's, but after getting 3 pairs of midweight boot and one of heavy over the calf a year ago I've not worn any of my Costco, smartwool, lorpen, or anything else except my kenetreks a couple of times. They're still in near perfect shape, and I wear them literally every day, standing/walking all day. It's time to purge all others from my sock drawer. I just got 3 pairs of lightweight for summer wear about a month ago, equally pleased. A place called gobros.com runs 25% off a couple times a year, making them like $17-20 for most options. I could not bring myself to spend the money for so long, but so glad I did.
