Hubby has been complaining that his feet have been getting beyond cold and he can't really feel how cold due to sciatic nerve being pinched and his feet are partially numb. This concerned me as he spends a lot of time working outdoors and did not want him getting frostbite!! So I bought him these socks. He is now wondering where have these been his whole working life. He says he takes less breaks to warm up as it make a huge difference. I would 100% reccommend these to anyone that spends a lot of time outdoors or if you even have bloodflow issues and have cold feet these will 100% keep your toes toasty warm!!! What are you waiting for grab a pair!!!
