Just bought the footprint version, and played for 3hr on hard court this weekend.
joints feel great (normally feel pain in ankles, knees, back - and have to rest for 1-2d before playing again).
also bought the original artilage version per
@chikoo recommendation... will update (and compare) after playing in them
[edit] Update - i have flat feet, and wanted to share my experiences
- Artilage - more cushioning (at ball of foot area), and more arch support (too much IMO); but pushes my pinky toe to the outside... i took them out of my tennis sneakers, and moved them to my snowboard boots, where side to side stop and go should be less of an issue
- Footprint custom ortho - feel ok, cradle your feet after doing the oven and mold step, but i prefer the FP flat better. the arch support is slightly less than artilage (good for me).
- Footprint flat - most comfortable to me, because it doesn't push my pinky toe to the outside, and still provides excellent cushioning
I had "Superfeet" in a bunch of sneakers, i took them out and replaced everything with "Footprint flat". Superfeet should be worried, their business is about to tank.
I am 8.5, and i found that all above fit perfectly (no need to size up)
