Material:

Upper: Suede leather with waterproof M-Select Dry membrane (taped seams for increased waterproofness)
Lining: Thin textile lining
Outsole: Quantum Grip outsole with good traction

What we love about these shoes:

Wide toe box
A flat zero drop sole
Low shoe weight
This shoe is somewhat of a compromise barefoot shoe: It has arch support and a relatively stiff outsole. Therefore, the shoes are best suited for a beginner in barefoot shoes.

Fit and size advice:

Fits a narrow to normal-width foot
Fits a low to high instep
True to size, see size chart below.

Membrane: Regularly treat with Collonil Protect & Care for better resistance to water and dirt.
