Joma Viper - Men's Sports Footwear

The Joma Viper for Men are not just another pair of shoes. They are an invitation to run the way running was meant to be: from the foot, from within.

No gimmicks, no cushioning that steals your strength. Just your body, your stride, and direct connection with the ground.

Their breathable technical-knit upper hugs your foot without squeezing it, offering lightness and freedom in every step. The VTS ventilation system keeps your feet cool and dry even during intense training sessions.

And under your feet, an important decision: 10 mm total thickness combining midsole, outsole and insole. A real balance between comfort and the ground feedback barefoot running demands. Just enough to protect you, and enough to feel.

Want to feel even more?

Remove the removable insole and let the ground speak to you without filters.

The high-resistance rubber outsole provides grip and durability, following each stride naturally, and its ZERO DROP design restores the biomechanics your body understands: aligned posture, efficient movement, real stride.

These shoes don’t take you forward. They bring you back.

Because when you run freely, there’s no finish line: there’s a path.

Run with who you are. Not with what they tell you to be.

My size in the Joma Viper Barefoot Men

To find your size, the best option is to measure your foot and click on the “Check your size here” link located below the size selector.

If you’re between two sizes, choose the larger one for a more relaxed and natural fit. Your toes should have room to move and expand freely.

And if you don’t get it right the first time, no worries: you can easily exchange the size. The process is quick and free if you activate the 1.99 € exchange insurance (valid for mainland Spain and Balearic Islands).

Care and maintenance

Clean them with a damp cloth and mild soap. Do not use a washing machine or dryer. Let them air dry, away from heat sources. Remove the insole to speed drying and maintain hygiene.
