答案:Orthopedic sandals are designed to provide support and comfort for individuals with foot, ankle, or lower limb conditions. They often feature arch support, cushioning, and a stable base to help alleviate pain and correct posture. Pylera is not a recognized term in the context of orthopedic sandals, so it might be a brand name, a model, or a misspelling. If you're looking for a specific product or brand, it would be helpful to have more information or context.
