The Thoknia instep-strap is an additional strap that fits over the top of your foot and provides a greater degree of fixation. Use them as an additional fixation for technical trails with steep inclines, large rocks, for muddy trails, or in combination with our amphibious sandal, the Zaros.
For road running most people don't use an instep-strap, but if you start using them in other terrain you usually end up using them everywhere.
