4 easy fixes to solve foot pain in cracks

4 Tips to Make Foot Jamming Comfortable

1. Get the Right Shoe Setup

Your shoes make or break foot jamming. You need a flat shoe, but more importantly, your foot inside the shoe must sit flat. I’ve sometimes seen climbers turn up to Crack School classes in flat shoes, but because they sized them down 3 sizes, their toes are completely bunched up inside!

So what do you need:

• Flat foot in a flat shoe: No aggressive downturns or tight toe curls.
• Wide toe box: Stops the sides of your foot from getting crushed together (which increases the foot’s profile).
• Low profile on the sides of the shoe: Especially down the pinky-toe side.

2. Find the Depth "Sweet Spot"

We often say with crack climbing, "get as much of the body part that is useful and doing the jamming action in the crack as possible." But don't confuse that with "get as much of your body into the crack as possible, full stop!" There is a big difference between what is useful and what is detrimental.

With foot jams in a hand-sized crack, there’s a subtle balance to strike:

• Too shallow: Putting too little of your foot in means only your toe knuckles engage. This makes for a weak jam and concentrates huge pressure onto a tiny area (ouch).
• Too deep: If you have a slim, low-profile foot, you might push it so far in that the crack edge lies right across the thin, bony top of your foot. This might be fine for a couple of jams, but after a whole pitch, it gets very painful.
• The Sweet Spot: Aim for the crack edge to sit about half a toe to a full toe's length past the webbing of your foot. Here, the foot has plenty of surface area, the rock hits a softer section, and the rubber on your shoe takes the load.

Pro Tip: On longer stretches of crack, subtly change the depth your foot goes into the crack by a millimeter either side of that sweet spot, purely by feel. Having the crack edge lie across slightly different parts of your foot stops any single spot from taking all the abuse.

3. Lower the Heel

When you place your foot into a hand-sized crack and twist it, don't keep your heel level with your toes. As you start putting weight through the foot, gently drop your heel toward the ground so it sits lower than your toes.

Remember how we wanted a low-profile shoe, especially down the pinky-toe side? As you drop your heel toward the ground, that lowest-profile outside edge of your foot enters the crack much more effectively.

This accomplishes three things at once:

1. Gets more surface area of the foot inside the crack to spread the load.
2. Relieves direct pressure on your toe knuckles.
3. Gets a lower-profile section of the shoe into the crack, which creates a better jam.

By lowering the heel you aren't just relieving pain and pressure in your foot—you're getting a more secure jam at the same time, killing two birds with one stone!

4. Reset Your Expectations (Don't Overcook It)

Stop before it actually hurts! Climbers often expect their foot tolerance in cracks to match their general climbing fitness, but crack climbing is practically a different sport.

Think back to when you first started climbing. Your forearms pumped out quickly, your skin was tender, and your body needed time to adapt. Foot jamming is no different. Even if you’ve been climbing for 5 or 10 years, your crack tolerance starts back at zero because your body hasn't built up to these specific pressures yet.

Don't let your general climbing fitness trick your mindset into expecting veteran crack tolerance on day one. Reset your expectations, listen to your body, and give yourself time to build that tolerance gradually.

Happy jamming,
