All our shoes go straight into the machine. First, remove the insoles and laces. Slip your trainers into a delicate bag (or even a pillowcase) and toss them in the washing machine. Choose a gentle cycle with cold water with your favourite mild detergent. When the cycle is done, shake off the excess water and let them air dry without going through the tumble dryer. Do your shoes need a bit more attention? Change the laces and insole, and they will be like new.
