Welcome to seebreeze and an awesome sport Kikeee91
Drury is spot on about you buying the wrong kit.
Get yourself a flat-rocker light wind board with handles and foot straps to complement your new gambler (it is your high wind machine and next year's trick board

).
don't beat yourself up about stuffing up your first board purchase. You won't make the same mistake again!
if you can't afford the next board, buy one of these and stick it a little in from the heel-side rail to grip the board's edge:

any scrap of eva bonded with Selleys kwik grip or shoe sole glue repair will do just as we'll and give you that grungy look and feel (the you can buy those boots you so want for your second season!

)
happy to help and hope to see you on the water spreading the good stoke!
