Flexi bindings were invented by Eric Philips in 2002 to combat the alarming failure rate amongst boot and binding combinations on polar ski expeditions. He skied on the prototype all the way from the Siberian coast to the North Pole, without failure, and spawned a new era in extreme-cold bindings. Flexi Vintro is engineered to withstand the most brutal ski expedition on Earth, a North Pole full-length expedition. It'll do that, over and over and over.
Available in regular and wide (formerly known as NP and Oversize). How to choose.
Vintro is built on Flexi's Ultima System, a revolutionary concept in ski touring bindings. Click here for a full range of Ultima System features.
This is the ultimate system for the most brutal conditions. The reinforced boot harness, made from premium-grade 25mm webbing, is attached to Flexi's side-walls via double cam-slots. Once cammed in they never move. Step into Flexi Vintro, pull the oversized tensioning strap to secure the boot and you're away. One hand, one easy action! The straps automatically adjust to any boot size, with additional adjustment at the cam-slots for super-size. To exit, place the tip of your ski pole through the release loop and push with the basket. Free in seconds without bending over. After a few uses the straps retain a memory of your boot shape. Fitted with high-quality acetal buckles for cold tolerance.
Although Flexi Vintro's come 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. You don't need to use both bolsters per binding, just use as required. A set of 4 Bolsters is included with each pair of Vintro. More details.
