94 / 100 based on 10 expert reviews

  • 100 / 100 | Two in Tasmania

    [T]hese are going to last us many many years so it's well worth considering three or four season boot like this Scarpa SL Active.

  • 100 / 100 | Outdoors Magic

    We’re not massive fans of 3-4 season boots for non-winter use here, stiff soles make more sense when you’re kicking into snow or wearing crampons, rather than on hot summer mountain days, but that’s personal preference and some people will choose to use them all year round.

  • 92 / 100 | Live for the Outdoors

    A solid performance from the standard-bearer for the 3-4 season category, but there’s no women’s version.

  • 90 / 100 | Active Traveller

    Yes, these are pricey boots, but build quality, performance and looks are all first rate and for anyone who is serious about their winter walking the SL Activ has to be worth checking out.

Updates to Scarpa SL Activ

  • The Scarpa SL Activ is the revamped version of the SL M3. Among the key changes in this redesigned version is the addition of a heavy-duty rubber rand at the base of the upper which its former self lacked. 
  • This updated model is constructed with a technology called Activ Fit. Absent in the previous build, this technology gives the boot improved stability and a more streamlined fit. 
  • Scarpa engineers gave this footgear a semi-stiff midsole. This kind of build quality puts the SL Activ under the B1 category which makes the boot compatible with C1 – strap-on crampons. 

Scarpa SL Activ size and fit

Scarpa’s SL Activ is a high-cut boot crafted specifically for male backpackers. Its fairly true-to-size fit is intended for wearers with regular feet. It comes in a range of half and full sizes. It is built on the BD last, improving the user’s foothold and giving the boot the right amount of volume for more cushioning. The gear’s speed lacing system provides a custom lockdown. 


Preventing backpackers from sliding or losing their footing over various types of backcountry surfaces is the Vibram Biometric outsole. It is based on the XS Trek compound, allowing it to stay durable for longer and remain responsive even in wet conditions. Its self-cleaning lugs are engineered at opposing angles to provide multi-directional grip


The Scarpa SL Activ has a dual-density PU midsole for terrain stability and comfort underfoot. It comes with a dynamic TPU shank which gives additional medial support. Right on top of this stabilizing component is the Activ Plus footbed. It is made of memory foam, granting familiar comfort over time. 


Covering the foot safe from the elements is the SL Activ’s HS12 Sherpa leather upper, complete with a fabric liner courtesy of 37.5. Its sturdy thickness (at 2.7 millimeters) offers support and a level of scuff resistance. Its full-on rubber rand further bolsters the boot’s defenses against abrasions.  

Completing the upper’s equation is the boot’s quick lacing system. It uses synthetic laces and combination eyelets made of metal.
