This A2 boot is designed a little higher compared to the A1, causing increased support in the ankle area without hindering the necessary freedom of motion. Because the shell is mainly containing fiberglass, deformation of the boot to adapt to personal fitting is more easy compared to the A1. The shell of the boot isn’t less stronger at all, only slightly more heavy due to the carbon present in the shell. In all positions more padding is used compared to the A1, causing increased comfort. The other side of the coin is that this also results is a slight weight increase compared to the A1 boot, where minimal amount of padding is placed.
