La Sportiva features Vibram Nano in the Synthesis Mid GTX

The outsole of La Sportiva’s Synthesis Mid GTX features the Vibram Nano equipped with the proprietary Impact Brake System (IBS). The asymmetrical design of the lugs delivers traction and grip. It also aids in shock absorption, hence reducing fatigue.

The opposing, slanted position of the lugs on the soles raises the braking power by 20% (on average) and lessens impact forces by 20% (also on average).

CMEVA + STB technology combo for the Synthesis Mid GTX’ midsole

The La Sportiva Synthesis Mid GTX uses a compression-molded EVA midsole (CMEVA). This material is durable and provides torsional structure, enabling better control of foot rotations. The abrasion-resistant, elastic TPU inserts render support.

La Sportiva Synthesis Mid GTX STB

The STB technology makes the heel area rigid. This component wraps the midsole (along the heel area) and unifies it with the upper. It also allows a secure lockdown fit.

Enhanced cushioning

The Synthesis Mid GTX has an Ortholite footbed for cushioning. With its open-cell structure, it is breathable and can manage moisture inside the shoe. The footbed is removable so hikers can replace it with their desired orthotic insert.

Synthesis Mid GTX’ upper gives more comfort, less weight

La Sportiva Synthesis Mid GTX breathable upper

The upper of the La Sportiva Synthesis Mid GTX uses an AirMesh fabric and PU leather. This combination yields breathability and durability. Likewise, the Nano-Cell Technology that wraps the shoe helps maintain its structure.

La Sportiva Synthesis Mid GTX Gore-Tex

The Gore-Tex Surround utilizes the open construction of the Gore-Tex film that allows aeration from below the foot. It works in conjunction with the side ventilation outlets. As a result, the foot stays dry, reducing the risk of having blisters.

La Sportiva Synthesis Mid GTX single-pull lace system

The Synthesis Mid GTX also uses an adjustable single-pull lace system that has a metal ring eyelet and speed hook on the top. This setup enables the user to open the mouth for easy on and off. The elastic band near the instep reduces flopping of the laces.
