Alpinestars SMX Plus Boots Review and Sizing Info from STG

  • Alpinestars SMX Plus Boots Weight Alpinestars SMX Plus Boots Weighed 2.35 lbs for 1 boot in a size 45 Euro on our shipping scale.
  • Alpinestars SMX Plus Boots Sizing We feel most riders will need to go down 1 size in the SMX Plus Boots to get a proper fit. Using Van as a benchmark he wears a 12 US in most shoes that offer average to above average width. He wears a size 45 Euro / 10.5 US in the SMX Plus Boots. Rider feedback on sizing also supports ordering 1 size down from your normal size.
  • Alpinestars SMX Plus Boots Performance Van's opinion: The Alpinestars SMX Plus Boots feel broken in straight out of the box, with excellent mobility and feel for smooth operation of the controls. Comfort while walking around and while riding is class leading IMO. Comparing this to other Race / Sport Boots like the Alpinestars Supertech R, Sidi Mag-1 and Dainese Torque D1 Boots the ankle support has more movement built into it which increases both comfort and feel (overall ankle protection is reduced a bit as compared to the others mentioned).
  • Who are these boots right for? The Alpinestars SMX Plus Boots are an excellent choice for BOTH Race Track and Street riding. With the Alpinestars SMX Plus Boots you get the protection you need with the comfort you want off the bike walking around. We recommend this for riders shopping for boots that are protective and comfortable to be used on the street and track or a combination of both.
