Vivobarefoot and its two ways to feel the trail running: Firm Ground o Soft Ground

Vivobarefoot revolutionizes the outdoor movement and trail running with two new soles for minimalist footwear focused on very different terrains. The objective is to be able to enjoy with the maximum sensations of the whole spectrum of lands that nature offers us.

Firm Ground (FG) and Soft Ground (SG) soles span the entire terrain of trail running, from the rockiest to the FG, to the most muddy, with SG.

Before going into describing the differences, let's look at the common characteristics. Both soles are 100% minimalistic, respecting parameters as important as zero drop, flexibility and width for the part of the toes. Of course, they do not have any system that provides stability or try to control the tread; We already know that these systems do not help , hindering the correct movements of the foot, while preventing the development of all its potential structure and sensitivity.

Vivobarefoot Firm Ground

The Firm Ground (FG) sole is designed to move on hard, stony, dry or wet terrain. Its drawing recalls the footprint of some bird, with lugs of 3 mm height. The lugs are distributed throughout the sole, to feel more the tread and ensure an optimal grip in both dry and wet trails. These multidirectional lugs cover the entire sole, except in the area of ​​the arch, where they are replaced by small multi-lugs. It is made of PRO5 , a thin, durable and resistant layer, five times more resistant to punctures than a standard sole of the same thickness; And with an outsole of TRb Rubber , a strong rubber, non-marking that provides a high resistance to abrasion.

The stack height of the sole, taking into account the different layers and the tacos, is 6 mm, not counting the inner insole that own all the mountain models of Vivobarefoot. If we count this insole, the thickness rises up to 9 mm.

Vivobarefoot Soft Ground

The Soft Ground sole is designed to run on muddy, snowy, or slippery terrain. The sole, similar to that of the old Vivobarefoot trail models, offers a completely redesigned design with aggressive V-shaped lugs that are separated to prevent mud build-up. Gum compounds are also new. It is made of PRO5 , a thin, durable and resistant layer, five times more resistant to punctures than a standard sole of the same thickness; And with an outer sole of Eco Rubber , a rubber made from recycled tires that provides a high resistance to abrasion.

The stack height of the sole, taking into account the different layers and the lugs, is 8 mm, not counting the internal insole that own all the mountain models of Vivobarefoot. If we count this insole, the thickness rises up to 12 mm.

Two similar soles in minimalistic performances, but different depending on the terrain which do you prefer?
