Review: Alpinestars S-MX 3, ehe balanced boots

Reviews and tests 2 October, 2014

We analyze...

Here we have versatile boots where comfort combines with a high degree of protection, without neglecting the clean, contemporary design lines and a very anatomical profile.


As mentioned above, the new Alpinestars S-MX 3 are urban boots, which is to say that they haven’t been designed for Sports riding. Having said that, we have to admit that nowadays there are few urban cut boots that have the number of protections that are incorporated into the S-MX3. They are available in various colours, but all of them keep these sober lines that allow them to be used in an urban environment and for day to day use, blending with different dress styles.

The outside of the boot is made of microfiber, which guarantees the great durability of the footwear, as well as a correct protection against abrasion and adverse weather conditions. On the inside, which maintains permanent contact with the bike’s chassis, we have straight lines, whose aim is to ensure an optimum feel at all times, aiding the bike-rider connection.

In the area of the instep and Achilles’ heel we find a flexible material in the form of an accordion, which allows for a wide range of movements.


As previously mentioned, although they have been designed for optimum comfort for everyday use, the Alpinestars S-MX 3 incorporate many reinforcements and inserts for protection giving them that extra security that few boots of the sector can provide. As an example we can highlight the reinforcement used in the shifter area, as well as that of the shin plate. The outer part of the heel and the side of the ankle have high quality TPU reinforcements, a rigid material that protects these areas from eventual abrasions and knocks. The external part of the ankle is of the same material but of double density, for greater protection in this area.

Looking at the front part, we see that the outer edge has an integrated bi-injected slider which is removable. Also, the sole of the boot extends to the toe box, thus helping provide optimum rigidity in this area. Lastly, inside the toe box we also have reinforcement for greater protection and durability.

Fastening and adjustment

The Alpinestars S-MX 3 incorporate a lateral zip system on the inside face of the boot, covered by two Microfiber Velcro flaps, whose function is to protect and conserve the zip fastener and adjustment. Apart from this zip regulation, in the instep area there is a buckle closure system on a double density TPU support with a micrometric fastener in order to customise the adjustment of the boot to the anatomy of each user and at the same time provide greater structural integrity.


The sole of the Alpinestars S-MX 3 has been made of high quality polyamide and has reinforcements in the area of the toe box or arch. The sole has an exclusive compound rubber that incorporates grooves very similar to that found on wet or “grooved” tyres that are used in competition. The main aim of these grooves is optimum water dispersion.

Other features

The inner lining is of breathable material with non-slip reinforcement in the ankle area, keeping the foot well secured. Also, we have inner padding in the ankle area for an optimum fit and maximum comfort. Here we have to highlight the great feel and comfort that these boots offer, allowing us to carry out any errand with the comfort of sports shoes and with most of the features of a motorbike boot. The anatomical foot-bed is of EVA foam and Lycra and is removable, as well as providing an optimum fit and breathability.

Each Alpinestars S-MX 3 boot weighs about 700 grams approximately and has European certification for motorbike footwear EN 13.634.
