MKS Fit-Alpha Sprint straps (not to be confused with the lower-cost Fit Alpha Spirit) are handmade in Japan from two layers of glove-soft leather with a tough layer of anti-stretch nylon in between.
You may never need the added strength of twin rivets on the buckles - which ensure that the straps don’t self-destruct under the explosive power of Japanese Keirin riders - but it’s nice to know these straps have your back (or at least your feet).
