Many customers of the SteriShoe UV shoe sanitizer have also gotten laser toenail therapy. Laser light therapy offers incredible potential as a therapeutic option for treating everything from pain to toenail fungus. Over the years, light device manufacturers have fine-tuned their ability to control the precise output of laser light so that it treats the affected areas, while leaving surrounding healthy tissue alone. The trouble is that many insurers refuse to recognize laser therapy due to the lack in objective research. All that is poised for change, though, as a greater understanding of how laser therapy works reaches the public, creating an increase in demand for these procedures.
