Get lots of advice on how to walk. Sounds stupid, I know...you've been doing it for a thousand years. But your pressure points will be different. Keep an eye on thickening skin. Pressure on such points can lead to wounds.

I kid you not. I lost my big left toe about 7 years ago and I have to be very careful with my feet. I seem to have more problems with my right foot (all 5 toes) than my left foot, but it's all because my weight distribution is different than it was some years ago.

Best of luck. And get some good shoes!!
