The DS AX 90 features the same Power Cage construction as the DS, but in a wider 100mm last. Like the other DS boot models, the AX 90 features a sleek design with great power transmission, cosmetic appeal, and ease of entry/exit. Rearward support is enhanced by an ABS plate integrated in the cuff, with dual canting on the inside and outside. On the medial side of the lower shell, a special textured surface allows us to provide the power transmission of a thicker material without the added weight. A lightweight boot board with superior insulation enhances warmth, with an extra shim included to help raise the heel if needed. All DS models fall under Dalbello’s MyFit customization system, with both the Instant Fit Performance liner and shell able to be heat molded.
