Sinch is a sinch to sinch.

We introduced Sinch to take up the slack between our Vintro and Paramark bindings, offering extreme-cold touring functionality with ease-of-use ladder straps and ratchet buckles. Tested on multiple polar outings, we back the durability on all but sustained North Pole expeditions. Each pair comes with a pair of short, medium and long ladder straps to accommodate any size boot.

  • short, medium and long pairs of ladder straps
  • all replaceable parts
  • offset mountable
  • heel locators provide torsional rigidity


Available in regular and wide. How to choose.

Ladder straps and ratchet buckles

High-quality ratchet buckles are riveted to two 25mm webbing straps that attach to cam slots on the boot cage wall. The no-tool straps allow for fast and easy adjustment to your boot bulk. 

During our ladder strap R&D, we froze multiple materials down to -40c in an industrial test freezer and placed them under severe load; only DuPont Hytrel came out unscathed. We then field tested Hytrel on expeditions across Greenland and to both poles, a combined 1300km and 65 days, and it came up trumps. Attached by 304 stainless bolts, washers and Genloch nuts, we provide 3 sizes of ladder strap per pair allowing you to chop and change depending on your boot. Each ladder strap has a lug on the end to keep it retained in the buckle making boot entry and sinching, well...a sinch!

BOLSTER KIT

Although Flexi Sinch comes in two widths, Bolsters take up any remaining play you may still have between your boots and sidewalls. Easy to install, simply release the straps in the cam slots, insert the bolster and re-engage the straps. A set of 2 Bolsters is now included with each pair of Vintro. More details.
