DeepskierTramp skis suck you get like a foot of air but if you really want to You can a buy a pair of foam short ones that blow ass cheecks and are spendy take an old oair of skis anr rap them in duct tape and shoes or the best option is go find and buy a long foam sled draw out your design (graphic and shape) then cut them out with a hot wire cutter and tape shoes on or drill holes in them and run shoelaces and maybe some tape to make bindings that fit everyone the only problem is they can be week and fold so you might wanna slide a small thin biece of wood like wall trim in the middle so they dont fold and tear
SV.lukastaylormy buddy just took a foam sled and cut them into a ski shape. He said they worked alright.
RsimpsonThe foam sled thing will work decently but it might fall apart kinda quick. Just to screw around and try some different things I like to tape pool noodles to the sides of my feet to practice grabs and change up tricks/ get interesting and you could probs put some ankle weights on to make it more realistic
My Friend an I have done both of the Foam sled and the noodles, Both worked well and we still have them but sadly no tramp anymore. Mine were the pool noodles and I made bindings out of duct tape. After a while the noddle started to rip around the front and back of the "Bindings." To fix this I cut out some cardboard laid it over the splits and duct taped it over. That added strength as well as kept the edges from flopping around so I could actually get some grabs. I would never use stiff skis for fear of hurting yourself or ruining your tramp but I can vouch that with the pool noodles or sled they work great, you don't loose to much bounce once your use to them, and they can be mad fun when you get the hang of it. Plus we stole some noodles from the local pool and had ductape at home making this project $0. My friend also used and old belt for a "binding." Hope that helps if you really want I could get pics, if it doesn't work your probably out like $10-$20 max.
