New Bauer Supreme UltraSonic Senior Hockey Skates Size 7.5 Fit 1 (US Men’s size 9 Narrow). The new Fit 1 is similar to the former Vapor D width. That has been extremely popular over the years. Normal Vapor users will feel at home in the new Fit 1 which features a shallow heel pocket, low instep, and low volume to allow for the tightest fit around the ankle wrap as well as narrowest of the 3 fits. The Carbon Curv composite boot is the stiffest and most powerful offering from Bauer, which has been further improved this year with the Unibody Outsole. By wrapping the carbon outsole up the sides of the quarter package, the Ultrasonic can better transfer energy through each stride. With the increase in stiffness, Bauer wanted a complete range of motion so players can squeeze every ounce of power out of their stride. The Reflex Tendon Guard, Reflex Pro Tongue, and Flex Facing provide enhanced mobility over the top of the foot and through the peak of the stride, all while remaining stable and locked in.
