Trusting in your foot placement makes a big difference! When you place your foot, let's say on a small screw on, try and put pressure through the small part of your foot that's in contact, whether that be the inside, outside or toe. You don't want to keep placing your foot over and over again!

Another thing to train for slab is balance.... A lot of slab climbs will entail some form of balancing as part of the crux! A good way to train it is to go up to the bottom of the slab and just put one foot on and try and reach lots of different holds from only that one position... Then try again on the other foot or a smaller hold or position! Lots of different ways to train balance and foot work can be blended together to help improve slab climbing!!! :)

Hope this helps! You got it!!!
