Walking on a bumpy, packed sand surface is supposed to be better than an even, paved surface for your feet and leg muscles. That’s what the company MBT came up with a few years ago and this season shoes with the but-busting concave soul have been released by many brands. Avia is one of those, but they created a double rocker, or the rocker concave soul with an air pocket under the arch. Three models include the ishape, iburn and iquest. The negative heel, double rocker and low density forefoot in each shoe model claims to make downtime activity productive by building muscles in the leg and quads – those muscles in the rear. This is done by making you work for every step by rolling your foot over the shoe’s soul.
Avia has a history of innovation since its beginning in 1079. Soleredemption.com has an interesting profile on the company’s progress.
