Sustainability when it comes to fashion doesn't end below the ankles; it's time to treat your feet to the luxury they deserve while sticking it to fast fashion at the same time. Clothes Doctor and Socko have paired up to bring you the ultimate treat for your feet, in a giveaway worth £100.

Socko £50 voucher: Win £50 to spend on Socko's sustainable socks; choose merino wool for a luxury feel, or recycled cotton, made from plastic bottles! Even better? Each pair comes with a mending kit and a 3-step darning instruction guide to encourage repairing or reinforcing rather than throwing away. You're sure to find the foot-loving pair that's right for you.
