This is probably the stiffest boot I've ever stepped into. I didn't get a chance to ride on them, but they are top notch quality. I've found in the past that a stiffer boot means more discomfort, but not for the Malamute. Salomon knows what they are doing! I didn't feel a single point of discomfort no matter which way I flexed, dipped, or twisted in these suckers. It gives you rock solid support with a super cush liner that feels like cashmere. I could only afford the Synapse, which are much softer, and not quite as nice but I wish I could have had the coin for these Malamutes, I would definitely pick them up!
