Technical, high-performance motocross / off-road boot for entry-level youth riders. Brand new design for impressive performance, comfort and safety at an astonishing price.
Features:
- Specifically designed for up-and-coming youth riders with smaller feet.
- Advanced closure system inspired by the Tech 10. Features strong techno-polymer buckles for easy adjustability with a precise, secure and streamlined fit.
- Comprehensive support and security built in to the external/internal structure of the boot minimizes lateral flex and the risk of hyper extension.
- Sole provides superior durability, grip, feel and a high level of structural rigidity.
- Anti-bacterial innersole designed for extra support and improved comfort.
- Injected high modulus PU shaped with a profile that provides high level of impact and abrasion resistance.
- Featuring an additional insole (included in sizes 10-11-12-13-1-2-3-4) which has been specially manufactured to be one size smaller than the boots actual size.
- Allows the rider to initially wear the boot with the modified development insole until their foot grows sufficiently to use the standard insole, extending the life of the product.
What we think:
The Alpinestars Tech 3S Boots (the “S” stands for Short) are a mid-height version of the full-size Tech 3, designed for youth riders, smaller adults, or those who prefer a lighter, more flexible boot for trail riding, dual-sport, or casual off-roading.
While not as protective as the full Tech 3 or Tech 5/7 models, the Tech 3S is a practical choice if you want a lightweight off-road boot that offers decent coverage without the bulk of a full-height motocross boot.
✅ Alpinestars Tech 3S – Key Features & Strengths:
-
Mid-Height Design:
-
Covers above the ankle and lower shin—ideal for riders who find full MX boots too tall or stiff.
-
Especially good for younger riders, smaller adults, or trail riders looking for more flexibility.
-
-
Protection:
-
Injection-molded TPU shin plate and reinforced toe box, heel counter, and ankle zones.
-
Not CE-certified like higher-end boots, but provides solid impact and abrasion protection for its class.
-
Steel shank midsole for arch support and rigidity on footpegs.
-
-
Comfort & Fit:
-
Soft interior padding and mesh liner for all-day comfort.
-
Three adjustable buckle closures (vs. four on full-size boots) for quick and secure fit.
-
Minimal break-in time — softer and more forgiving than Tech 5 or 7.
-
-
Sole:
-
Durable rubber compound sole with good peg grip and moderate off-bike traction.
-
Fully bonded (not replaceable), but holds up well in light to moderate use.

🔍 Final Verdict:
The Alpinestars Tech 3S is a smart choice if you:
-
Want a shorter off-road boot that’s easier to walk in and move with
-
Are a youth or small adult rider, or just want less bulk than a full MX boot
-
Do trail riding, light dual-sport, or recreational dirt riding
It’s not meant for motocross competition or high-impact jumps — for that, the full Tech 3, Tech 5, or Tech 7 are better.
If you're riding mostly trails, pit bikes, or tight terrain where agility matters more than full protection, the Tech 3S is an ideal match.
