Product Details

The Alpinestars Tech 7 Enduro Drystar Boots are designed for riders who need serious off-road protection with added waterproof comfort for wet, muddy, and unpredictable conditions. Built for enduro, trail riding, dual sport, and aggressive off-road use, these boots combine the support of the Tech 7 platform with a waterproof and breathable Drystar membrane.

TPU protection helps shield the shin, ankle, heel, toe, and lower foot from impacts, while the biomechanical pivot system supports natural flex and helps stabilize the ankle in rough terrain. The reinforced lower shell, integrated metal shank, and protective toe cap add strength and support for standing on the pegs, handling technical sections, and riding through demanding off-road conditions.

The Drystar membrane helps keep water out while allowing moisture vapor to escape, making these boots a strong choice for rain, mud, puddles, and wet trail rides. An extended microfiber gaiter helps reduce water and dirt entry, while soft ankle and collar foam improve comfort for longer days on the bike.

An enduro-specific high-grip double-density sole provides traction when walking, pushing, or dabbing in rocks, roots, mud, and uneven terrain. Self-aligning quick-release buckles and broad calf adjustment help create a secure, personalized fit, while replaceable sole components help extend the service life of the boot.

Sizing Info

Alpinestars Tech 7 Enduro Drystar Boots generally fit true to size for most riders, but the waterproof liner and protective structure may feel snug at first. Choose your normal boot or shoe size, but size up if you are between sizes, have wider feet, or plan to wear thick off-road or adventure socks.
