Ice blades grip the ice for the length of the blade, no squirming, inlines with 3 wheels only touch the ground for a few centimeters, there's no actual grip, the hard boot holds the foot securely, a leather boot wouldn't give enough balance to the body, a hard shell is something for the body to push against, the transfer of torque happens between the foot and the hard shell boot, the transfer of torque with ice skate happens at the blade on the ice.

Why don't roller skates use hardboots?
Because the transfer of torque happens at the plate.
