The metal lever clicks into place with a satisfying snap, and the tension adjustment feels much more precise than my worn-out original. These replacements fit perfectly and gave my boots a new lease on life for the rest of the season.

Had to replace the original buckle on my boot after a season of hard use, and this pair fit perfectly on the cuff. The metal lever feels much sturdier than the plastic ones I’ve used before, and it clicks into place with a satisfying snap.

Installed these on my fourth position cuff and the metal pin mechanism is noticeably smoother than the original plastic one. Took about five minutes to swap both sides with just a small screwdriver.
