The toe has been the same for a long time because it has proven to be the safest on the market, The heel for one thing has all the screws under the boot; there is no plate/screws behind the heel therefore there is no deadspot on the ski besides what is created by your boot. The other reason being that the pivoting heel is safer when releasing, its a consistent release pressure that is required, this makes it true to din, there is no need to crank up your bindings, It is really one of if not the safest binding out there
