Lucy Trail 3/4 Socks Review
This is the second time I've ordered these socks, the first time was last month. I've now doubled up on these edgy merino blend socks because they are top shelf quality, uber comfortable and smooth to run in. They are great running socks and to have Lucy B's initials embossed on is just the cherry on top.
