Overall Rating: :
The Crux is a universal approach shoe that will take you from the car to the base of any climb. The super sticky Vibram® Vertical approach sole climbs effectively, and provides superior traction for managing alpine terrain, easy climbs, and descending loose terrain. The webbing ribcage reinforced with Kevlar secures the forefoot for technical climbing precision and superior edging control. Microporous EVA provides cushion for long hours in the hills while toe randing rounds out the protective qualities. Suede uppers mold to the foot for a comfy fit all day long.
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 love these shoes! I am a hiking guide here in southern utah. The crux is my go to shoe from light hiking to technical hiking. They are ultra comfy! Break in period was easy. I have a wide foot so I did my lacing like a running shoe and they fit awesome!

Bought these shoes after reviewing a few similar products. Best in looks and feel. Scarpa fit my feet perfectly with nice room in the toe box for longer approaches. Good quality fit & finish - what I expect from a reputable company. Only recommendation would be to have an additional pair of laces with them out of the box.

Took these as my only boots on a 300K Monsoon Trek to Tsum Valley and Manaslu. Fantastic grip on wet Himalayan trails with mega-exposure. Comfortable, stable, all-good for all terrain. Washed the mud off them and used them in Malibu last week!

I LOVE THESE SHOES! They are not only my approach shoes for climbing, they are my everything shoes. Walkin' down the street, see something climbable, got my approach shoes on, climb it with ease and look like a pro while doing it. Also a great climbing shoe! I'm comfortable in them up to 5.10's, after that you want wall specific shoes. Again, I LOVE THESE SHOES!
