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® brand closures 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

Alpinestars Supertech-R Boots 4.6 5 50 50
Broke within a month Loved these from when I first got them. They were a bit tall so my foot had a little bit of travel up and down in them but I was expecting this because of the way my feet are. I did expect more air flow through these but if I lifted my foot a bit I got a ton of air flow. Almost exactly a month after I got these the pull string to tighten these broke. I was able to tie a knot to temporarily fix the issue and continue riding. The ratchet strap on the left shoe was not able to stow the tab end inside of the calf either. July 25, 2015
Nice boots, definitely run big Returned Sidi ST's to give these a try- Wasn't impressed with the protection on the ST's. Sizing: I have an average width foot and wear size 10 or 10.5 in most brands (New Balance, ES, DC, Etnies, DVS etc) For comparable boots, Sidi's in 44 fit me great. I ordered these in 43 and they could probably work, but I'm going to drop down to a 42 since these are still a bit long in length for me. I assume the 42's will be a tiny bit narrow, but these do have some stretch so i'm sure they'll break in. These boots are very comfortable and the inner bootie design is really a great feature. I still wish they were even a bit stiffer in the outer shell as well but having the protection close to the ankle feels more supportive than the ST's. Overall I think I'll be happy with them once i get the proper size, but definitely order AT LEAST one size down, maybe even 2 if you don't have a wide foot. June 8, 2015
Great purchase this is a great buy, just note they run a 1/2 size big. Great product from Alpinestars and love the removable inner bootie. Fits snug as they should definitely recommend July 20, 2015
Great boots with tricky sizing To help out others who are trying to figure out the sizing... My feet measure almost exactly 43 according to many foot measurement devices that you see in the shoe store and they're about medium/average width. My running shoes are size 10 (Saucony or Salomon), which leave about 0.5" to 0.75" of space in front of the toe for swelling. I like my motorcycle boots relatively tight (like race/track gloves) and had been wearing size 42 Dainese Axial Pro In, 1st gen Alpinestars SMX , and Alpinestars Tech 8 MX boots. When I switched to an Alpinestars suit from Dainese, I started shopping for a new pair track boots. To get the same fit, the equivalent size for these Supertech R is 41, which is 2 euro sizes down from my actual feet length. I recently tried on the latest (2013?) SMX Plus and not surprisingly, size 42 was spot on. One very minor gripe for the Supertech is that the leather flap on the top of the boots would fold in between the boots and the suit when being active on the bike. My calf size is average and I'm not sure if I could tighten the strap any further. You could also see that in the photos of many pro riders. Overall they are very fine boots functionally and aesthetically. Hope the sizing notes help! July 18, 2015
Great boot! These are the best boots I've ever worn. Protective, stylish, and wonderfully comfortable. May 9, 2015
Easy to wear easy to fit The inner liner makes these boots fit like a glove, in fact I ordered two sizes and had a difficult time determining the better fitting because the inner liner hugs your foot no matter the shape or size. Ended up choosing the size that was slightly more snug than an everyday shoe. If you have a doubt I would err towards the smaller size in these. Great flexibility without being limited by stiff leather or other devices, and all internal mechanism except for one means less things to shear off in a slide. Also bought accessory magnesium toe slider because of reviews over the plastic oem toe slider...they look great but are slightly thicker than the oem toe sliders. June 4, 2015
Great track boot Very lightweight and cool looking boot. Provides lots of support and has very good ventilation May 2, 2015
Amazing fit and comfort These boots are the bees knees... I tried on every possible boot from every company... Dainese fit too small, sidi too wide and stiff... The super tech R is as good as it gets... With the inner boot you get a perfect fit around your foot that then slides right into the outer shell for the best comfort and mobility that you can find... Break in was non existent as these things felt great right off the bat.... I'm typically a size 10.5-11 us as far as shoes go... These run a bit small as a size 41 so if possible try them on somewhere if you can... I'm lucky enough to live within 10 miles of the revzilla boutique in Philadelphia :) so trying gear on and getting advice is simple for me... April 13, 2015

Fletcher R: Tried SIDI ST's which just weren't nearly as supportive as their appearance suggested. Hoping the close fitting inner bootie brace on these will offer better protection. Jun 1, 2015
B R: because gizmodo review convinced me to buy good equipment in case i crash. Jul 28, 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?

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

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
