I'm using the stock thin insole to keep as much depth in the skate as possible. The original Jetspeed skates are a perfect fit for my feet(6.5). The FT1 7.5 skates are the same length as the original Jetspeed but the depth is very shallow. That was the only problem I had asked about before purchasing the skates and doing the custom scan. They assured me that the depth would be adjusted to accommodate my foot.
Shogun, they're 7.5 but they're the same length as the original Jetspeeds at 6.5.
