As so many of us are working from home at the moment and the temperatures are gradually sliding, I have noticed that my feet are getting chilly. And so I have invested in Lounging Socks - which are basically chunky, toasty, lambswool socks with a lining to keep feet snug as a bug all day! In this case the lining is made from recycled plastic bottles so they have an eco-pedigree as well! There are two sizes - 1 for men and 1 for women - and they are extremely generous.
Lining: 100% Recycled PET (polyester from water bottles)
