La Sportiva TXS GTX Hiking Boot for Men, Black/Yellow

The La Sportiva TXS GTX is a technical hiking boot with a mid-cut shaft designed for hikes with a heavy backpack, via ferrata, and approaches over rock and scree. It is part of the TX series, which La Sportiva originally developed for approach shoes, and incorporates its grippy Vibram sole and rubber toe cap into a waterproof hiking shoe. The GORE-TEX Extended Comfort membrane keeps moisture out, while the abrasion-resistant mesh makes the shoe lightweight and breathable.

La Sportiva TXS GTX: Hiking boot with Vibram Megagrip and GORE-TEX

The upper consists of a highly abrasion-resistant mesh that is surrounded on all sides by a rubber scuff guard. At the front is a shock-resistant rubber toe cap that protects the toes and upper from contact with rocks. The differentiated lacing system with metal hooks allows for two zones of varying tightness: tighter at the bottom for a precise fit on the forefoot, and looser at the top for greater freedom of movement at the ankle. The 3D Flex System at the ankle allows the upper to flex forward and sideways without losing stability, ensuring a secure footing on uneven terrain.

Sole and Cushioning

The Vibram Megagrip outsole with a 4-mm tread provides traction on wet rock as well as on forest floors and gravel. The Impact Brake System—featuring oppositely arranged lugs—slows you down when walking downhill and reduces strain on your knees and joints. The injection-molded EVA midsole with STB Control inserts provides both cushioning and stability, while the sturdy insole prevents the shoe from collapsing under heavy loads. The heel-to-toe drop is 8 mm, with a stack height of 24 mm at the heel and 16 mm at the forefoot.

Who is the TXS GTX designed for?

For anyone who goes on summer mountain hikes with a pack, via ferrata routes, and rocky ascents, and wants a shoe with ankle support but without the weight of a classic leather boot. Weighing about 510 g per shoe, the TXS GTX is significantly lighter than typical trekking boots, yet offers enough protection for alpine terrain thanks to its stiff insole and toe cap. If you’re mainly hiking on soft trails, there are lighter alternatives; if you need precise footing on rocky terrain, this is the right choice for you.

Size Selection and Fit

The TXS GTX fits true to size and is cut on a standard last—it is not a wide fit. Size 43 corresponds to UK 9 and US 10. If you’re wearing thicker hiking socks, choose your usual size; if you have very wide feet, we recommend trying them on in-store. The shoe requires almost no break-in time; the mesh is soft right from the start.
