Overall Rating: :
Evolved from SCARPA’s classic SL M3, the SL Activ is a very supportive but exceptionally light backpacking boot incorporating SCARPA’s new Activfit technology. Activfit includes the highly cushioned, lightweight, dual-density Biometric PU midsole package, which puts different densities of polyurethane into specific locations to improve both cushioning and precision on the trail. The new more ergonomic upper design is made from Sherpa HS12® leather, and lined with memory foam with moisture wicking and odor control for a custom fit you will appreciate on long trips. A full perimeter rubber rand provides protection, and long-term durability and support in rough terrain.
SizingSCARPA Sizing Chart
Measure your foot with a ruler, using cm or inches; convert to Euro or US using this chart. If you need mondo sizing, please refer to the SCARPA chart on this page/tab. We recommend you purchase two sizes, the size you think you are plus one .5 size bigger for fit testing at home. As long as the products are in like new condition and the packaging is 100% intact, we will credit you for the returned product.
General fitting rules depend on the product's intended use... follow the appropriate guidelines below for best results.
- The bigger/heavier/more supportive the product, the more you may want to upsize .5 - 1full size. Lighter, softer, more supple shoes can be sized closer to your measured size.
- Note: SCARPA Plastic mountain boots all use UK sizing; UK converts easily: 1 full size smaller than US men's size, 2 sizes smaller than US women's size.
- Try on with appropriate socks for your usage. The bigger the boot, the more appropriate a bigger sock (sounds crazy, huh?)
- If you use orthotics or already have aftermarket footbeds, measure against the standard footbed in boot. Fit into boot for sizing/fitting the boot.
- Best to try on at the end of the day when your feet are larger/swollen, than when your feet are fresh to ensure good fit after a long day.
- Lacing can play an incredibly important part of a good fit. Be sure to play with lacing when analyzing fit.
- Make sure your heel isn't slipping.
- Make sure your toes aren't hitting the end.
**Approach shoes may be sized smaller for performance purposes but beware... small shoes are really uncomfortable on the trail.
Rock climbing shoes
- From your measured size, you'll want to consider downsizing .5 - 2 full sizes. The flatter the shoe, the closer to your measured size; the more downturned/aggressive the shoe, the more you'll want to downsize.
- The best fit is comparative between sizes and only you will be able to judge that, though an experience climber could offer good insights to your fit.
- If it feels painful, it may break in... or it may not.
- Pain sucks as a rule of thumb though and makes climbing miserable.
- Only you can judge what's 'acceptable' discomfort.
- Good fitting rock shoes shouldn't necessarily be 'comfortable' by walking/running shoe standards.
- Look for looseness/bagginess in the toes and heel. Bagginess can mean 'slop' when climbing with feet perspiring, etc.
- Toes should completely fill the toebox.
- Heel should feel solid; like they won't pull off if heel hooking.
- Any foot movement in new shoes will mean sloppy fit when broken in.
- From your measured foot, convert to US size using the scale. Translate the US size to Mondo size using the SCARPA mondo scale (not 'true' mondo conversion)
- Shell fit: taking liner out of the shell and inserting foot, toes touching end of shell but completely flat.
- Should have 1.5 - 2 fingers of space behind heel and heel of shell (between 14mm - 20mm)
- Too little space = go up one shell
- Too much space = go down one shell
- If not sure... fit test BOTH shell sizes
- Put on a ski sock for gosh sake!
- Use and orthotic? Put it the boot (after taking out the standard footbed).
- Put foot in boot AND BUCKLE IT! You can not tell a boot fit without buckling it
- This will pull your heel back into the heel pocket, relieving cramped toe space
- Boots do pack out! A 'comfy' fit when new will mean slop later.
- Regardless, your toes should NOT be pressed against the end of the liner
- Get your Intuition liners molded! This provides THE BEST FIT available.
- Any minor pressure points or space will be eliminated by molding
- Find an experience SCARPA dealer for fitting/molding
- Boot fitting is an incredible service and generally requires a service fee of varying amounts... it's worth it though!

My back feels so much better. Replaced my Garmont boots which I couldn't find any and was surprised.. found my"sole mate." I am going to buy a back up pair. Every time I find something I like they quit making it. The only problem I do have is that I have to keep cranking tighter on the laces specifically around the ankle.

Exceptional support, durability and comfort, especially with the wider toe box. Warm, dry, light weight. My main complaint is that the finish color of the leather easily wears out to a light burgundy color and there is no way to restore the original finish color. Shoe polish doesn't work. NikWax helps a little, but leather stain/color just wears out, even with light use! Maybe European environmental laws forbid traditional, durable analine dyes? Otherwise great boot. Sole is sturdy, grips great, self cleaning cleats/sole pattern.

Yes these are men's boots but I just love them. They give me fantastic ankle support, keep my feet warm, and I have wiggle room for my toes. Very comfortable boots! I have a messed up left foot and have not experienced any pressure points. Can't tell you enough how pleasant it's been on long treks! Thank you Scarpa!
