Spot covering seams, edges, and stitching that may irritate the skin
This is an Open Cell Foam padding, which makes it very flexible so that it can easily conform to the natural curves of the body. The Open Cell design makes this padding more breathable but it does need to be replaced if it gets wet.
In general, memory foam padding is meant to be changed every 4-8 weeks depending on wear, which will keep the leg brace or boot cleaner and fresher longer.
Signs that indicate it's time to change padding include:
padding is wet, matted, or dirty
padding begins to peel
As with most padding materials, this padding can be used in combination with other companies' braces, boots, and devices.
