Can the kybun sole be repaired?

The kybun sole is designed so that as its surface is worn down, its elastic springy properties are reduced. The kybun sole is well known for its lack of wear and tear and under normal circumstances, you should not notice any significant adverse effects within the first 2 years. If this is not the case, it may indicate that the wearer is either heavier than normal or they have a foot misalignment or gait defect.
