98mm last, 100 progressive flex, shock absorbing boot board, and heat moldable liner and shell. At 549$ CAN, this is one of the top park boots on the market right now. For those like me with skinny legs, the power strap with the clip will really help with support, although after a while I found the clip to tighten the strap too much, and I was just using it like a regular power strap.
The only cons I find are that the bottom clip is located too much on the top of the foot, which causes pressure points. Although it is bearable, I would've prefered a 45 degree clip.
I haven't heat molded the shell, but I would recommend it if you want to maximise comfort.
The toe box will feel tight when you first put the boot on, compared to other boots, but after heat molding them, they'll be just fine.
