In reply to professionalwreckhead:
You're right, learning how to trust your feet when trying to protect the belay is not the best idea.
I suggest you do the following every time you go climbing, especially when at the climbing wall or out bouldering:
Find a boulder problem:
1 Examine its footholds and look for the perfect part of the foothold to use.
2 Think about the best part of your foot to use on that foothold
3 Place your foot on that foothold slowly and deliberately, making sure you use the part of the foothold and your foot that you decided on in stage 1 and 2.
4 Count the number of scuffing noises you make when doing the boulder problem.
5. Repeat, trying to reduce the number of scuffing noises to = 0.
Once you manage to reduce this to 0 then find a new boulder problem to do this on. Pick boulder problems of every imaginable style and you will develop a wide repertoire of different types of footwork. E.g. do it on slabs one day, walls the next, overhangs the day after.
This exercise is called silent feet, if you apply it diligently for a while then placing your feet in this way will become automatic. I imagine that you'll be able to do moves 3 technical grades harder.
Enjoy
