Using these New Balance 847V4 walking shoes is simple. Just lace them up tightly to ensure a good fit, and you're ready to go for a stroll. When it comes to cleaning, use a soft brush and mild soap to gently clean the synthetic leather and mesh parts. Let them air - dry. Avoid putting them in the dryer as it might damage the materials. Keep them in a cool, dry place when not in use. Since the measurements can vary by size, it's a good idea to double - check the size chart before buying. And if you have diabetes, these shoes are a great choice as they have the right Medicare / HCPCS code, but always follow your doctor's advice.
