Incredibly low shoe weight

Fit and size advice:

Length: True to size - take your usual size in these, but refer to the size chart below
Width: Suitable for a narrow to wide foot
Volume: Suitable for a low to normal-height foot
Toe shape: Steep slope from the big toe down to the other toes. If you have a foot where the second and third toes are as long as the big toe, you may need to go one size larger to accommodate the little toe side.

Vivobarefoot Primus Trail II FG barefoot shoes are a popular terrain shoe ideal for trail running, outdoor activities, or hiking. It features an outsole offering excellent grip in forests and fields, on both wet and dry surfaces. The outsole is thin and flexible, providing great ground contact. The shoe weight is low, making them feel as if you have nothing on your feet in these barefoot shoes!
The upper is made of a water-resistant material, making Primus Trail the perfect pair of shoes even when it's wet and cold outside. The upper has a soft textile that breathes, with reinforcements made from recycled PET bottles around the toes and on the inner and outer sides of the shoe. Primus Trail can be adjusted for a good fit thanks to the quick-lock lacing - providing a snug fit around the ankle while the toe box offers plenty of room for the toes to move freely.
Care instructions: Wash the shoes by hand with, for example, Colloni Bamboo lotion and spray regularly with Collonil Protect & Care to extend durability and maintain the water-resistant membrane.
