My husband LOVES these socks with a Wolverine steel toe cap over the calf. According to him, with a steel toe cap, they are very comfortable to wear in work and hiking shoes. They never slip when worn, and the socks' soft sole and toe provide relief without feeling bulky. They don't stretch over time and I haven't noticed them thinning with wear or washing and drying. They won't discolor from abrasion or the elements like other brands of traditional OTC medications. I started buying these socks about 2 years ago and replaced his regular OTC products with these hard working shock absorbers. They are not frayed, frayed or frayed and I honestly can't tell socks I bought 2 years ago from new ones. These Wolverine steel toe boot socks are well worth the price, I can't recommend them highly enough.
