Review on Pairs Merino Heated Winter Thermal by Nick Ward

It's a bargain price but decent quality. They are not very thin and do not pose any problems with well-distributed silicone adhesive dots. My only comment is that they are small. I wear regular size 8 and size 9 shoes in some smaller running shoes and these barely fit. If you wear a size larger than 8, don't worry, they will be too small. If you wear a size smaller they are amazing value.
