Alpinestars Supertech-R Boots

The Alpinestars Supertech R boot is the newest high performance/racing boot, constructed with hi-tech micro-fiber and designed to meet light weight and performance requirements in top level racing. The front flex area is constructed with a soft TPU mesh with shaped reliefs for abrasion resistance and natural forward and back movements. Flexible accordion synthetic leather at Achilles allows natural movement. Top gaiter follows leg contour and is made of flexible high-grade synthetic leather reinforced with rubber for maintaining shape. Full length micro-fiber panel on inner side of the boot provides a smooth surface for excellent grip and feel against the bike and protects from abrasion and heat. A lightweight rubber compound sole offers excellent grip and feel and allows for natural flex as the rider changes position and pressure on the foot-peg. Strategically positioned ventilation in heel and shin TPU, and soft TPU mesh on forefoot guides air through the boot.

The separate inner boot works with outer boot to form a protective system and external TPU shin protection wraps around to outer calf and is engineered to spread and dissipate impact energy across the entire surface while remaining compact. Clip-on toe-slider provides excellent feedback and protects the outer toe box structure from abrasion. (Upgradeable to a magnesium slider). Replaceable TPU heel plate slider protects from impact and reduces friction in the event of an off. Outside entry/exit has stretch accordion panel for a close fit and ease of entrance and removal. Bio-mechanical ankle bracing boot has double hinged inner and outer torsion bars to progressively absorb flex and rotation stress on the ankle and reduce pressure and hyper extension injury to lower leg joints.  Inner ankle brace constructed with fiberglass charged polyamide and ergonomically designed closed cell padding for protection and comfort.


  • Extremely protective, flexible and comfortable with excellent aerodynamics
  • Flexible, lightweight toe shifter allows feel for changing gears
  • Zip mounted on accordion stretch panel gives easy closure with excellent fit
  • Velcro tab lock the zip pull closed, keeping it flat and secure
  • Micro adjustable ratchet top closure stows tab end inside calf TPU
  • Polyamide compound moldings around foot bed provide impact protection
  • Removable anatomic footbed is sculpted for precision fit
  • SUPERTECH R is CE certified

Awesome product Needed new racing boots and decided to go for the best that alpine star has. This is a great boot and very comfortable. Sizing chart was good and along with the revzilla sizing recommendations the boots were a perfect fit. March 24, 2015
Plastic toe sliders are no bueno Just wrapped up round 1 of AFM racing and I honestly am disappointed with the plastic toe sliders. I consciously kept my toes up as much as I could - I'm not perfect mind you, but the plastic toe sliders are just no bueno. They basically melted and guess what's right beneath that? The boots themselves. The only thing left in the end that separated my socks from asphalt were the inner booties which were almost melted through as well. A bit annoyed as these are incredibly expensive boots. :/ March 23, 2015
Beefy protection and comfortable I ordered a size 43, which translates to a size 9 US. I have another pair of shoes in a different brand that i had to get in size 10 US (Italian based company). Both boots had a break in period of discomfort. It was a little scary at first breaking it in because it's such an expensive boot. My pinky toe was sore for at first but after breaking it in, it was fine. I didn't want to be stuck with a boot that doesn't fit. Just make sure to keep the tags on and wear it around the house for several hours if you need to break it in. The inner booty makes this shoe so comfortable. The protection looks top notch, I have not been in a spill yet to test it out. I can sometimes feel a bit of circulation and cooling with the vented version. March 8, 2015
Excellent protection Excellent boots for the track, even on the road it feels great. only a little problem on the ratchet clip that fell off after two try but had it repair for free. comfort is good, great protection December 11, 2014
GREAT BOOTS! Money well spent. After some research, I got these for my first track day. When I buy safety gear, especially for high speed aggressive riding, I want the best. I'm not rich but I can't put a price tag on my safety. After my first track day and a few street rides, the boots fit pretty good and are comfortable enough. They vent VERY good and seem to be made strong. With big calves, the zipper seems to be hard to pull up over my leathers but with a little patients, not a huge problem and the rubber at the top makes a nice seal... and lets face it, They look pretty sweet too. I got the black, white and yellow and they look just like the product photo. I'm very happy with this purchase. December 1, 2014
Great Boots I recently had a low side on the track with these boots and man did they hold up. No tears in the leather, I believe the metal ankle slider and toe slider prevented most of the damage and also reduced the injuries to my ankles. Very comfortable boot as well and the ratchet and elasticated zipper make for a very secure fit. September 29, 2014
Best Motorcycle boots, that money can buy. If you're a motorcycle racer here you have the Best Boots that money can buy (MotoGP Style), never doubt it. Everything perfect, and as always RevZilla Logistics are awesome. 1000% Recommended. August 18, 2014
Excellent Boot! I was previously wearing SMX5 boots in size 45 and had a low side out street riding so I purchased these. I find that these boots have the same fit that the others did, no need to drop a size like some of the other reviews mention. I'm a 10.5 US size and that's what a 45 Euro equates to. July 21, 2014

Firas N asked: Hi.. I'm trying to figure out what size to purchase. The length of my right foot is 28 cm (11 inch) and the width (circumference) is 26 cm (10.2 inch). I'm considered to have a wide foot and my size ranges from 10 to 11 depending on the brand and shoe type (i.e., sneakers, boots, casual, dress, etc..). Could you please help me identify the best size to purchase?

Chris H: I purchased this boot in euro size 46 (11.5 USA). I normal wear a size 12 in USA. I have a wide foot and big calves. I found it to fit like a slipper with a little extra toe room. I wear a thick pair of riding socks and find it to be perfect. I felt if I went down to a euro 45 that it might be on the tight side (probably wouldn't need the thick socks) but the length (toe area) would be perfect. I wear these almost daily. Since your between a 10-11 I would go with a 44. These particular boots run 1 size larger than they call for. So if you wear a size 11 normally-go with a size 10. Which in this case will be a euro 44. Might be snug at first, but boots will break in nicely. Best boot I've ever bought. Wouldn't by anything else. If your worried about a tightness go with the 45 and a thick pair of socks.
Hopefully this info helps

John K: My best guess would be 44. My foot is about 1 size smaller than yours (9-10 in most other shoes), and also wide. I went to the Philly store last year and tried on several different boots. In the other brands I tried on - Sidi and Dianese - 44 was the best fit, but in the Supertech Rs, 43 was the ticket. I bought them and they fit perfectly. If they don't fit, don't forget about RevZilla's fantastic exchange policy. Mar 6, 2014

Correa R: Firas, my regular US number is 10/10.5 I got a pair on 45 which I felt a little big... afterwards got another pair on size 44 which were perfect! So if you are more to size 11 for shoes, I would go with size 45 for the boot, otherwise you should be fine with the 44! Mar 6, 2014
