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. 

Size and fit

Scarpa’s hiking boot, the SL Activ, is 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. 

Outsole

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

Midsole

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. 

Upper

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 leather hiking 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.
