I've had mine stretched 3 times. The effect seems to be temporary on the nylon fibers for me.

I don't have that much pain in my feet from walking. I also have sesamoid issues, and high arch, so I'd have to walk in them to see if either of those problems are aggravated.

I'll consider it, thank you. I only wear my Gravity Defyer's for short periods because of the toe box problem.

My next pair will be a New Balance. I've had great results from my current pair.

I use a special type of shoe lace that does not confine tightly the instep. They are curly and stretchy so compression on the top of the foot is much less. To find others in different lengths and colors Google
"coil shoe laces".

These are available online or at Famous Footwear locally.
They make it easy to put shoes on, as you don't have to tie them once they are laced in.

Also I use the alternative lacing pattern suggested by this site:

For people here with Tinel's sign on the top of the foot, alternative lacing can take pressure off nerves and reduce numbness and other symptoms.

I have several different biomechanical issues with my feet, besides the PN one. That is why I suggest all PNers to have a complete exam by a podiatrist to find any complicating factors.
