PERFECT for high arched feet! NOT LOW ARCH
on December 30, 2010
OK, this will get pretty technical, so bare with me. Just so y'all know my background here, I used to work for a podiatrist as well as for one of the world's largest running stores.
The way the Green Superfeet works is by providing support for someone with a HIGH arch. During the run, a high arch collapses and the green superfeet will actually help hold up the arch during the collapse. If you have LOW arches, do NOT buy this - use the blue superfeet. If you have low arches, this can actually cause plantar fasciitis by causing tension in the plantar facscia. I've seen many reviews saying it's great for low arches, so I wanted to give a heads up.
Now, the one real cool thing about the Superfeet is that they have the hard plastic bottom. This, contrary to what seems logical, is the most healthy shock absorption for your feet. Compare it to running on sand versus running on cement. if you run on sand, your joints work a lot harder, and your body is not able to absorb the shock as well, causing pain. If you run on cement, your subtalar joint won't splay outwards as much, causing the fatty tissue under your foot to take more of the shock. The Superfeet encourages this with a deep heel cup, so it supports your heel, forcing the fatty tissue to cup your heel, creating the best shock absorption ever.
My personal opinion on this? I have it in all my shoes! I own about ten pairs of green Superfeet - they last forever, and the toe is perfectly flexible for a great toe-off during running. There is also a small layer of dense foam between the plastic and where your foot sits, allowing your foot to make it's own "custom mold" into the insole.
