The leading performance replacement shoe insole featuring a cupped heel and molded arch for stability along with Sorbothane inserts for outstanding foot-strike protection. They are so effective that they have been approved and recommended by the American Podiatric Medical Association. The Ultra Work Sport Shoe Insole works well in athletic shoes, work shoes, and boots. Sorbothane is the only shoe insole material that absorbs up to 94.7% of impact shock; and unlike standard insoles, which can bottom out, compress, and lose effectiveness, Sorbothane Ultra Work Sport Shoe Insoles retain their support and comfort month after month. Lightweight and durable, they also breathe and make for a much cooler insole. Sorbothane rubber was developed to simulate the soft padding of the heel. This makes it the most comfortable and best cushioning insole rubber available. Unlike foam rubbers, it resists becoming hard or flat over time and lasts much longer than other insoles. RxSorbo insoles are proudly made in the USA at our factory in Kent, OH. For more information please visit www.rxsorbo.com.

Average heel thickness is 9mm. Metatarsal thickness is 6.5mm. Average heel drop of the RX Sorbo WorkSport Insole is 2.5mm.

So why exactly are RxSorbo shoe insoles MORE THAN JUST INSOLES? The main reason: they are NOT made of simple, gimmicky foam or gel like most insoles. They are made of an advanced VISCO-ELASTIC material called Sorbothane. Sorbothane is the leader in vibration isolation. It is the same material trusted by NASA, NASCAR, and countless other agencies and companies for their vibration isolation needs. RxSorbo insoles are recommended by Dr. Mark Mendeszoon.
