With my foot inside the new Tech 10, it felt snug in all the right places, but I actually felt like I could bend my ankle slightly better than I could in the older Tech 10s. The new high-impact, bridged aluminum buckle system is easier to adjust and close shut, unlike the previous buckles that needed a mallet to get closed. Riders with bigger calves may have some difficulty getting the middle buckle to reach its perch even with the strap in its outermost position. (I would suggest that if you can’t get the middle strap fitment correct, order another pair of top straps, which are longer.) My calves are on the skinny side, but the strap was almost at its fully extended length.
