Ben said some stuff that I had already read in articles about bio-mechanics and proper human movement. Basically, we are brain washed into thinking our feet need tons of support, when in fact it makes our feet muscles and ankles weaker and they basically stop firing all together. The vibrams allow activation of those muscles again, and the chain reaction within the nervous system results in better nervous system performance all the way to the floor, including prioperception.

Right now I'm just using the flattest shoes I have which are the ones I usually train in.....Adidas Adi-Racer F1s. I love them for calves, but used to use basketball shoes or cross trainers for legs. Now that I use the Adi-racers for legs, I have better ankle flexion and feel my quads better.

Apparently, Nike Shox are the worst possible shoe for training legs if you want nervous system activation and connection with your base.

If you get your ankle flexion to increase, your need for elevated heels will go away.

Also, I don't think everyone HAS to squat ass to grass to get big legs.....in fact I think some people with certain geometry get more constant quad tension by stopping a bit before ass to grass, or even slightly above parallel. I go ass to grass on most sets, but stop AT parallel on others, right when my calves and hams start to really touch.

Looking forward to trying those shoes.
