@marie1959 I found an existing discussion on laser therapy for neuropathy and thought your post would fit well there so you will see that I have moved it here: https://connect.mayoclinic.org/discussion/neuropathy-1/

That said, members such as @cshallow @banksnc49 @cwallen9 and @mikween have all been discussing laser therapy and may know more about this specific slipper you are asking about.

Where did you learn about this and do you personally have neuropathy?
