The Silver Cloud II, by CrocsRx Medical, is specifically designed with the diabetic foot in mind and is infused with Croslite Ag+, which is a medical grade of silver particles. The Silver Cloud II creates a natural anti-bacterial, anti-fungal and anti-microbial environment for feet. This model is perfect for anyone susceptible to skin breakdown, ulcers, foot fungus and infections. The protective toe front toe cap prevents injury to feet when accidental stubbing occurs without the addition of excessive bulk. The superior-soft footbed provides a gentle environment for sensitive feet, while the roomy toe box allows for use of a medical sock (like the CrocsRx Medical Orthocloud sock) without creating any tightness or pressure points on the foot. Circulation nubs are reduced to prevent ulcers and the seamless interior limits chaffing that may occur with leather-like material, where seams of stitching can be problematic. for more information about Croslite Ag+ The Cloud is APMA approved and carries the United States Ergonomics endorsement. Can be washed in mild detergent and/or disinfectant. Dry away from direct heat.
