    Fit is excellent; laces help improve tightness in midfoot; new soles offer better traction and are warmer; great for weight lifting and light running

    If you're starting with Five Fingers, this wouldn't be the smartest model to take because the thickness of the sole will not allow for much mistake in your running form, walking form, or jumping form.

    It definitely gives you a more barefoot feel than the regular KSOs.

Updates to KSO EVO

The Vibram FiveFingers KSO EVO is an all-encompassing pair of shoes that are actually shaped like actual feet. Each toe even gets to be wrapped entirely by its fabrics and systems. Made from durable components, this running shoe ensures the comfort and safety of its wearer, keeping the performance as lightweight and natural as possible without sacrificing quality protection and efficacy.

The upper unit of this running shoe uses durable polyester to ensure that it stays intact, even after many uses. It is not stiff in form, so it allows the foot to be as flexible as it is able. The inner lining features a soft mesh that’s not irritating to the skin. A speed lacing system permits fast adjustment to the fit, therefore keeping the coverage easy to manipulate.

The Vibram FiveFingers KSO EVO utilizes individual toe slots, which change its façade to actually look like the shape of the human foot. The purposes of this design is to enhance the natural dexterity and versatility of the foot’s movements, enabling the toes to splay naturally and let the shoe adapt to the runner’s own biomechanics.

The sole unit uses 2mm EVA, which isn’t much compared to the usual thickness of running shoes’ mid-soles, but it’s meant to be that way because it aims to deliver a barefoot-like running experience on all types of terrain.

The outsole uses a high quality compound that is created to withstand abrasion or wear. It is able to hold onto a variety of surfaces with ease, making sure that the running experience of its wearer isn’t limited or restricted to just flat surfaces. It can even handle trail adventures.

KSO EVO size and fit

The Vibram FiveFingers KSO EVO is true to its size. The sizing scheme that is used for this model follows the regular measurements when it comes to length. Its width is medium, so it allows those with medium sized feet to acclimate well to it when wearing it. Its semi-curved shape follows the natural curvature of the human foot.


The Vibram XS Trek is a rubber material that is of high quality make. The durability of this section is reliable; it doesn’t easily wear off or lose its efficacy, even after many uses. Traction over the surfaces is very much afforded to the runner.


The platform of the Vibram FiveFingers KSO EVO is very flexible. It allows the foot to move naturally through the gait cycle, making sure that the focus is given to the preference of the wearer, in terms of performance.

A 2mm Ethylene vinyl acetate foam is used as the underfoot cushioning system of this foot-shaped shoe. It is comfortable and it provides mild comfort that’ll make each ground contact easier and smoother.

The Drilex® nylon covers the EVA foam. It features anti-microbial and anti-moisture capabilities, thus keeping the interior as clean and healthy as possible for the foot.


Durable polyester makes up the main upper fabric of the FiveFingers KSO EVO. It covers the foot well, hugging it snugly and securely. It even allows air to enter the shoe in order keep the foot cool and dry.

The lining has polyester mesh, which is soft and smooth. The runner can even wear this without socks, as it doesn’t make the coverage feel irritating.

A speed lacing system makes it easier for runners to adjust the fit. Only one tug from the laces and the shoe will be able to feel adequately tight or loose. No knots are needed for this.
