Does anyone have any suggestions for insoles that would be good for walk/jogging for a person who is overweight and has high arches with supination (rolling out)?

The custom orthotics my podiatrist gave me don't really help the supination.

Thanks,

This isn't quite what you were looking for, but you should try to find a great pair of sneakers with lots of support. Go to a specialty running store and they can fit you for one that will really help you. It may be a bit pricier than just going to a department store or something, but I think it's worth it to find a great model of shoe. Then, I find them on sale for subsequent pairs

I've got the same problem, and I've found that the Mizuno Wave Runner line of shoes offers good support. I use them when I'm walking the dog or when I'm running on the treadmill, and they keep me from getting shin splints or having foot pain.

What works for person 1 won't necessarily work for person 2. Go get fitted at the best running shop you can find.

The combination of heavy person and supinator is going to be difficult to fit; most really sturdy shoes made for larger people are for over-pronators. The Brooks Beast (horrible name, isn't it?) is the best-known of these.
