Alpinestars S-MX 5 Vented Boots

The S-MX 5 has been created as a performance road and track boot, incorporating the latest technical footwear design and material know-how. Following on from the other performance boots in the Alpinestars range, the S-MX 5 is notable for its comfort, hugging fit, safety performance and ease of adjustability.

  • Durable, high-tech micro-fiber upper construction offering a high level of flexibility
  • Double injected PU shields the shin, ankle, calf, toe and heel from impact while minimizing abrasion
  • Inner protection is given by a double injected panel connected to the heel counter, hidden beneath the outer shell and running up the outer ankle
  • Quick drying polyamide lining is laminated with open cell foam and high density contoured padding to absorb shocks to the foot area
  • The S-MX 5 boot is CE certified
  • Innovative air vents at the ankle, heel and forefoot are covered with a specially designed mesh to provide unmatched levels of rider comfort
  • Large ‘throat’ profile instep and Achilles flex bellows for superior flex and comfort
  • MTP mesh liner and anatomical, removable, PU Foam foot bed keeps the foot cool and comfortable
  • A fully vented version is also available in Black
  • Innovative inner (medial) side entry opening/closure system that features an elastic mounted zipper with an extra wide Velcro® flap, to give a precise, comfortable fit and wide opening aperture for ease of access
  • Highly ergonomic, lasting for ultra precise fit
  • Exclusive compound rubber sole features structured shank reinforcement for added support to the arch area
  • Interchangeable bi-injected PU toe slider with snap-in assembly

Great purchase! I bought these for my boyfriend and he seems to love them. They look really nice, great quality and seem to be good protection. He wears a size 13, so I ordered the size equivalent to a 12.5 since 13 isn't an option. He says they fit great though! December 29, 2014
Very poor customer service from AlpineStars Excellent customer service from Revzilla---extremely poor customer service from AlpineStars. Received boot from Revzilla. Within an hour of putting the boot on, the toe slider fell off. I don't drag my boots (ride a touring bike) so it wasn't from usage. I contacted Alpinestars via their email contact form for a replacement. No response. Contacted them again. No response. Called them and they stated they don't replace these....even if one fell off or was defective. I talked the customer service rep into replacing it. A month later, it still hadn't arrived. Called customer service and was told it was shipped and delivered. I didn't receive a tracking number or an email...was told they don't do that for replacements....it was delivered. Well, it wasn't delivered. I asked for them to re-send (remember this probably costs them a dollar) and they stated that they would not and that this is actually Revzilla's problem. Really? So....I call Revzilla and problem fixed in 2 minutes. I'll not ever buy a product from Alpinestars again, but will probably only buy motorcycle gear from Revzilla. November 6, 2014
Excellent item for protection and style These boots are great for riding. I wear them every time I go riding. They are very comfortable and they bring a lot of protection. I only wish they were more breathable but that's my only con for these boots. September 22, 2014
Great road boot I'm a new rider and was trying to find the best road boot. I had narrowed it down to the SMX-5 and SIDI cobra air. I've heard that all who try SIDI's stick with them, however that was not my experience. The Cobra's were right in the calf fit, but too big in the foot. The SMX-5's fit perfectly all around and have good protection. Highly recommended. May 27, 2014
Great protection for your feet!! I commute between school and home, and wanted a boot that would be comfortable enough to wear at school but also provide more protection than a pair of shoes. I chose the smx-5's because they offer great protection for your feet, but also your heels, ankles, shins and calfs. The shin protector is also small enough that you can get a pair of jeans over them. The only issue I have with these is that my feet are not that big. I usually wear anything between a 9 1/2 to a 10 depending on the brand of shoe I get. I ordered a size 43 and they fit right but I wish they were a little tighter around the ankle, but other than that I really like these boots. I also got the vented version, and you can tell, especially when on the highway. The little vents really help to keep your feet cool and dry. May 20, 2014
Love These Boots! I've been riding for 25+ years, and these are my favorite boots by far. They fit great (true to size) with no comfort issues...and the venting is awesome. April 9, 2014
Nice Everyday Boot Bought this boot to wear everyday close to home. Great fit, true to size. Breaks in very quick, comfortable to walk in. Nice airflow. Toe slider not very durable, but good feel. Probably buy the waterproof version of this boot. April 3, 2014
First Astar purchase Good quality,and comfort.Boots fit great,tight fit under straight leg jeans.Only rode with them a few times,but so far I love'm.They aren't exactly causal hangout boots or are they full on track boots,happy medium.I'll wear them when I ride down port with the wife and to my first track day.
