The cheaper ones seem to have good reviews. They are a different composition and higher in wool % than the Darn Toughs, which kinda makes me think they would "pill up" faster than DT's. They show a pic of a guy pulling the calf down which shows a fuzzy heavier weight looking material on the inside. DT calves are the same on the inside as outside which leads me to believe that along with the higher wool count that they might be warmer up top than the DT's. I'm wearing the 1466's in Lime right now (they are not lime, btw- they're different shades of gray as far as I can tell). I'm counting 11 different "panels" of different weaves and types of material all over. They truly do not bunch up or sag or anything anywhere. They always look like they do on the mannequin or model foot or whatever. The People Socks show a diagram with 4 different panels. They also don't mention any kind of warranty like the lifetime no questions asked deal with DT. Grumpy mentioned tight on the calf and I can see that as they are snug, but not tight on me. I'm 5'9, 185,size 11 and the Large 1466's fit perfect on me but I'm sure if you need a slightly larger calf version, DT probably has something designed to fit.
I've since bought 3 more pair for my Mother in all girly designs and they seem like a lighter weight version of mine. She said something about Bombas- I figured this was some BS she saw on Facebook or something, but they also look like a good brand. Bombas has a similar warranty to DT, and claims to have donated 10 million pairs of socks to homeless shelters FWIW.
One thing I just learned from reading comments on the PS is that you should wash them inside out. Will do this with the DT's from now on. People also claim that you can wear them several days and I actually tried this out and yessir you can. Called it at 6 days of one pair of socks but showering mostly each day and they truly weren't funky.
It seems like DT has figured out their sock game. Should be for $22/pair. Maybe buy a 4 pack of the People Socks and one pair of DT's and let us know how you like them. At this point I've already bought into the DT brand and like them enough that I'm just going to stick with these and then maybe try out their warranty in a few years.
