In a laboratory, the shoe is immersed in water to mid height on a mechanical arm that simulates a number of steps.
From this test we are able to establish how long and how many kilometres the shoe can withstand and remain dry.
- 2,000 flexes, around 30 minutes hiking
- 10,000 flexes, around 3 hours
- 30,000 flexes, around 8 hours
- 50,000 flexes, around 12 hours
We then validate in the field and rain that the shoe withstands this in use.
