I have a pair Gravity Defyer shoes. They help me walk better, mostly I think since the shock to the knees and hips is less. For people with heel spurs these coil in the heel shoes can be very helpful.

I have seen reviews online that buying them online is iffy....fit is not
really good, and one should really go in person to a store that
carries them. The website has lists of stores you can visit.

I think the quality of the assembly of the shoes is less than
Nike or New Balance, but I like the coils in the heels for these myself. Read reviews however before buying, as they are expensive.

I see this website has new versions. The older ones had a logo of a ---cough cough-- sperm! When I asked the sales person about it she laughed and said it was a tadpole... but I don't like it on my shoes. I see they have dropped the little sperm fellow.

This one is similar to mine...

I don't think the toe box is as roomy as other shoes, and that might be an issue for some PNers.

I know a guy who bought a coil shoe and it was over $300.
