How to use: Just slip your feet into the Drew Jimmy shoes and adjust the hook - and - loop closures to your comfort level. You can also remove the insoles if you want more space or to insert your own orthotics. Notice: Make sure the closures are not too tight to avoid discomfort. When walking, pay attention to the rocker bottom design which helps with the natural gait. Maintenance advice: Clean the shoes regularly with a soft brush and mild soap. Let them air dry away from direct heat. If the insoles get dirty, take them out and wash them separately. Replace the insoles when they start to lose their cushioning.
