When choosing a binding there are two main things you should consider.
1) DIN #:
DIN is the scale of the force release setting on your bindings. It is important to have the appropriate DIN for your weight to ensure they are safe!
2) BRAKE WIDTH:
Your brakes need to be wide enough to fit over your skis, but you don't want brakes that are too wide otherwise they will catch on the snow. Use the information below to choose the correct brake size for your skis.
90 or 95mm brake = Whipit ski
95 or 110mm brake = Allplay and Masterblaster skis
110 or 115mm brake = Vacation, Metal and Friend skis
NOTE: If you don't prefer a specific binding brand I would use the information above to decide what will work best for you because in my opinion Look and Marker make the best high performance bindings on the market! If you already prefer a specific brand that I don't offer then go for those! My skis will work awesome with any standard bindings.
If you are still unsure... ask me!
