Simple cold feet can quickly become a big problem for anyone with a condition like Raynaud's. IOMI Heat Holders Raynaud's Socks have a soft brushed double thermal layer that provides 3.1 TOG warmth measured as some 8 x warmer than basic The socks do this by using advanced Japanese designed thermally insulating yarn that also has superior moisture breathing abilities and softness, which is then increased by knitting it into a long looped cushion pile. That pile is expertly brushed into a super-soft fleece fibre to maximise the amount of warm air it can hold, to keep feet cosy and comfortable. Iomi Heat Holders Raynaud's Socks also have slim-resisting treads on the soles so they can be worn safely around the home.
