Butyl Rubber
Schoeller®-Keprotec
This fabric is made using only the highest quality of materials. It contains kevlar, which compared to its weight is 5 times stronger than steel. That's pretty impressive for a shoe. And that's why I can guarantee you these shoes will last you a very long time. This material will provide you with great protection, and it is also waterproof. So no matter what weather conditions you are dealing with, these shoes will maintain light weight and comfortable.
Duotech
This means that the inner side of the wedge is made of higher density foam than the rest of the module. Dense material on the inner side of the wedge will also make the shoe more durable, however, still maintaining the "light weight" property of the shoe.
I'm telling you, you won't have to worry about these shoes breaking down before you've gotten a good use out of them!

Fitlock system
The fitlock system is essential in the maneuvaribality of the shoe, which is much needed for any trail running shoes. It strongly supports the arch of the foot and makes the shoe feel like part of your leg. The rubber material also supports the bottom of the foot from harsh surfaces, and moreover the fitlock system makes the shoe go exactly where you need it to.
