Because we have the Edge Hybrid, we had to have the Edge SLS. The difference between these two is the mainly the closing system. Without the Hybrid SPIN system, this boot relies on a technology which also tightens your heel and shows off its light Stamina sole which brings a really cool look to the boot.
