I have got my kickflips down now and i recently tried doing stairs, i can get the spin and stay ontop of it and all but i usually dont land, land 1 foot or land it then fall of immediatly any tips

just make sure not to pussy because the most difficult part is committing 100% and getting your front foot back on. just focus on the board rotating and when you see the grip tape come 'round stop that ***** down

do a pop shuv it off

Just kickflip off the curb and work up. I am doing that now and I am working on doing a three.

Build up to it.

It's important that you have maximum control over your kickflips before trying them off things. Make sure you stay over your board and catch it. Stay balanced, I always leaned (?) to far back so when I landed i came in wheelie or tailstop.

the part about how you catch the board may help, start watching from about 4:40

Also, gotta be committed to it. That's all there is to it.

u have to be confident and have concentration and expect to land it. and try to lean forward a little when u land so u dont fall off.

ok the one foot part is probably youre scared. you might not think so but sometimes it just happens. in that case just focus on commiting and landing. when you do land and slip out its because your leaning too far back, putting too much pressure on the back foot. if you try and bend down and lean more forward, youll have an easier time. hope i helped
