Overview
Designed for long expeditions and tough conditions, the QST is grippy and supportive. We’ve updated the chassis to target sensitive articulations and wrap the foot for extra support, while also keeping your stride fluid. No matter how tired you are or how heavy your pack, the QST 4 ensures a stable yet smooth ride on any terrain.
Benefits
Enhanced stability
The new Chassis guides the foot, targeting sensitive articulations, even on the roughest terrain.
Smooth ride
Inspired by our trail running expertise, this backpacking shoe respects the natural flexion of your foot for a smooth ride that flows from step to step.
Enhanced support
Encasing your foot, the new Chassis also provides extra support around the heel and helps reduce muscle fatigue especially with a heavy backpack.

How to Measure Your Shoe Size
To find out your exact shoe size, follow the instructions below to measure your foot, and then use the charts above to find the appropriate size conversions.
- Get a ruler, pen, and piece of paper.
- Place the piece of paper flat on the ground and stand on it. Make sure your foot is flat.
- Make a mark behind your heel and another in front of your longest toe. If one of your feet is larger than the other, use the longer foot to measure your size.
- Measure the distance between the two lines in inches or centimeters.
- Find your measurement on the men's size chart above to determine your correct size. If your measurement falls in between two sizes, round up.
- If you can't find your exact size but still want to purchase the shoe, we recommend going for half a size up.
