Feel how your feet are released to give you all their strength over forest, mud and obstacle courses.

Vivobarefoot Primus Trail III SG.

If you're one of those people who doesn't look at the weather forecast because (although your mother tells you to wear a cardigan) you're going to go out and chase your goal, the Primus Trail III SG are your best companion.

This III version of the well-known Trail SG is still very resistant and with aggressive studs that guarantee optimal grip and traction.

Its sock-like fit fits the foot like a glove. You will feel it as part of your body.

As light as feeling that you have a sole under your feet.

That's why they are:

• Wide at the front: so that your toes can open up, preventing your toes from rubbing against each other and giving you and your knees full stability in every step.

• No reinforcements: so that nothing modifies the natural movements of your feet and ankles in any terrain position. Whether on flat or sloping terrain.

• Flat (no drop): so that nothing affects your posture. Making your achilles tendon have a greater range of motion, storing more elastic energy and releasing it with greater responsiveness in each stride.

• Highly flexible: so that your foot can adapt and stick to every shape of the ground, giving you more balance and control. Minimising the risk of unexpected twists and turns that lead to painful sprains and strains.

Why will you love the upper?

Because you won't have to stop for a second:

• With the adjustment around the ankle and the integrated tongue you will avoid the entrance of mud, stones, etc.

• It has a system of round cords with a quick release and insertion system.

And moreover:

• The fabric has different layers that offer almost waterproof properties.

• Highly breathable to facilitate water evacuation at every step.

Give it a go:

• Forest
• Mud
• Sand
• Steeplechase / Spartan Race

Its 5mm blocks are separated to avoid the accumulation of mud.

The V-shaped pattern will give you maximum traction in every stride, jump and turn.

It has a thin inner layer of PRO5 five times more resistant to punctures than a standard sole of the same thickness.

If you want more protection and thermal insulation, leave the 3.5mm Thermal Protection insole on with 3 times more thermal protection than a standard insole. Remove it to feel more of the ground.

The Primus Trail III SG Vivobarefoot is designed to withstand hard tests, with excellent grip on wet areas, mud and snow, and high flexibility allowing you to stretch, flex and move your feet without restriction.
