Created with your diabetic footcare in mind, Circufiber® All-Day Light Diabetic Crew socks feature our Circulight IR® Technology which has been clinically proven to increase circulation in the feet and lower legs. Our All-Day Light socks offer the same scientifically-backed benefits as the original All-Day collection but in a lighter, thinner sock, making it perfect for warmer weather and narrower footwear. The All-Day Light Crew sock is easy to get on and off, and non-binding around the calf yet structured to stay up, great for people at risk of foot complications.
