The ideal balance of lightweight and trail protection, the Spark is SCARPA’s award-winning Mountain Minimal trail running shoe designed for moving fast and confidently on rugged terrain. The low-to-the-ground framework with a 6 mm drop from heel to forefoot helps keep balance and stability on uneven trails. The lacing system works to secure the midfoot for precision running on technical trails, loose ground and long descents.
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!

I've had these shoes for about a year now and used them from ridge traverses in the Wasatch to long flat and dry trails on the Bonneville Shoreline Trail. They are a great shoe. The traction could be improved and deeper lugs would be appreciated. That said, it's a great shoe when traction isn't your main concern. Very fast and light and a good minimalist shoe. I would highly recommend!

Very light and comfortable. Much more of a running shoe than scrambler, but they'll do the job. Great fit right out of the gate, but Scarpa always fits like a glove for me (longer/narrow foot).

Comfortable feet often make or break my day and I have never been happier than in my Sparks. They offer a great combination of being lightweigh,t yet protective enough for when I attempt runs longer than what I have really trained for. I ran the Power of Four 50k in the Sparks, with no training runs longer than 17miles. At the end of the race my feet were in great shape, which hasn't been the case with previous shoes.

I've recently purchased my second pair of Sparks, which certainly says something, but wanted to share some performance observations. First off, as I have a narrow heel and foot generally, the heel cup and lacing system works exceptionally well to secure the foot without heel movement. The rubber and tread are fantastic and is certainly a testament to Scarpa's experience in footwear. Although minimalist, they do not compromise on durability or performance. Having heavily used my previous pair I am very impressed with their overall durability, keeping in mind their intended usage and expected life span. Excellent choice for avid trail runners.

There's a definite racing feel to this brand new shoe, in shops Spring 2013. Very light [275g, UK size 11], low profile and sitting on a more rigid outsole, they beg to be taken on Swiss Alpine paths -- rocky and fast. The Hi-Tensile fabric footstrike plate encourages you up onto your toes. In the world of lower profile shoes, despite the 6mm drop between the heel and forefoot (most work to around 12mm) these feel like they sit a little higher than other minimalist models which makes them a great introductory option as coping with barefoot-mimicking shoes does take some getting used to. Verdict: Ready for pacey, fast days on drier ground.
