This all creates a shock absorber like effect to absorb sudden blows and combat the degenerative effects of heel strike, which in turn enhances comfort and reduces fatigue. This footbed is our most popular and can be found in the majority of our boots. TheToughSider solegets going when the going gets rough!

The design enhances your performance giving you more grip and stability in rugged terrain. With built-in arch support, our ToughSider sole reduces fatigue and guarantees you a smoother ride.
