@nycgirl, I also have numbness in my feet but I still have some feeling and can drive OK. I've been taking supplements which I believe has slowed or possibly stopped the progression of my neuropathy. There already is another discussion Driving with neuropathy but it doesn't have many posts. Our Connect Director @colleenyoung may want to combine these 2 discussions.

The main concern I would have is if the numbness reduces your ability to safely drive I don't think I would want to cause an accident that would injury or take the life of someone else. The Foundation for Peripheral Neuropathy has a good article that you may want to read - Staying safe and independent and continuing to drive with peripheral neuropathy: https://www.foundationforpn.org/2017/03/06/driving-peripheral-neuropathy/

A few years ago I saw a demo of a device called Walkasins that attach to your legs that might be a good answer for you --- "Walkasins is a rechargeable wearable external lower leg neuroprosthesis for daily use, designed for those with sensory peripheral neuropathy to replace lost foot pressure sensation via gentle sensory signals delivered to the skin above the ankle." --- https://rxfunction.com/

I also have numbness only in my feet with my small fiber peripheral neuropathy. There are no cremes or topicals that will help with the numbness. @steeldove has experience with using hand controls for driving and may be able to offer some suggestions. Here is a post discussing the hand controls he uses -- https://connect.mayoclinic.org/discussion/anyone-here-dealing-with-peripheral-neuropathy/?pg=87#comment-283906
