Fit and size advice:

Length: True to size – choose your regular size for these but follow the size chart below
Width: Suitable for a narrow to wide foot

Toe shape: Steeply sloping from the big toe down towards the other toes. If your second and third toes are as long as your big toe, you might need to go one size up for space towards the little toe side.

The Vivobarefoot Tracker II FG is a true classic that stands the test of time and accompanies you on all your adventures. The Tracker is a hiking shoe well-suited for outdoor activities and trekking during spring, fall, and winter with a soft textile lining. The upper is made from high-quality leather with a water-resistant membrane. Vivobarefoot does not provide a 100% guarantee for water resistance, but by regularly using Collonil Protect & Care, feet remain dry, and the leather stays nice and soft for a long time.
The outsole is Vivo's Firm Ground sole providing excellent grip in terrain, even on wet surfaces. The sole is thin and flexible, allowing great ground contact in the Tracker. Initially, the Vivobarefoot Tracker feels slightly stiff in the materials around the heel, but it softens with use and quickly becomes a new favorite that will last a long time.
What has been updated in the Tracker II version is a softer inner lining and reinforced lacing eyelets.
