The Progressor 13 maintains a characteristically close fit throughout the lower boot (a touch more snug than the increasingly relaxed, modern medium fit) and up through the instep and lower leg before it flares out into a progressively more open boot top. Testers raved about the evenly draped liner feel and good fit match out of the boot, which only boded well for the fit changes that occurred in our custom Vacuum tests. Across the board the Vacuum process improved both fit and stance balance.
Testers liked the slightly more upright starting position of the upper boot. Flex feel was unanimously reported as firm but still enabled a natural and balanced amount of ankle flexion. Lateral stance felt neutral and offered easy access to inside and outside edges, turn to turn without any surprises. Comfortable and reliable arcs on all manner of terrain was the general takeaway on the Progressor 13 Vacuum.
