great outdoor shoe

This shoe feels amazing on your feet. The sole offers more grip but still feels very natural. You can still feel the different surfaces on the ground.

The new soles are great to keep your feet warm.
I'm gone love wearing these this winter :)

Nice Shoe

I like my new shoes, the feeling is excellent and the are very warm too. So I am very satisfied.

Another great shoe from Vivobarefoot

This is my first off road shoe from vivobarefoot (Primus FM, mens). Order and delivery of the shoes normal as expected. The shoes themselves (colour, details etc) are exactly as they appear on the website, which I am very pleased with. They came along with a pair of perforated insoles, apparently for quick drainage as the shoes are meant to be worn on the trail. Even though I still haven't worn them for a run, on wearing them at home without the insoles they run a bit large in length, though their width is normal for a vivobarefoot shoe. But once you fit in the insoles and try them on again they fit perfectly, still allowing for the necessary room for your fingers to spread while running. Thinking it over, I think its well thought from Vivobarefoot that the shoes run a bit large on length because when running long distances you can start your run with the insoles and take them off later at some stage when your feet start to swell. Overall I think its another great shoe from Vivobarefoot and long awaited for for trail running.
