You can but the back of pegs are very rounded so it can be difficult. I am considering adding a small piece of metal or hard plastic as a way to catch the peg with a boot to flick it open easier. Very easy to close, though.
The pegs mount high enough not to be in the way of break pedal, if I understand your question correctly. They do easily adjust front/back at least couple of inches, which should make it easy to find a 'sweet spot'. I am 6' tall and I used the farthest setting as I like to stretch my legs. You will also not rest inside of your legs on hot engine covers, legs contact the fairing.

I hope this helps.
