They're cool.I could of done with one of those last winter,i had to be dug out of my house,the 12 foot drifts would have made good jumps.Would have needed snow shoes though.
The skis on the front of the maxx with paddles on the back works good too though.

I just searched t-maxx skis on google,not that i normally visit BYT you understand.
I'd just adapt a maxx,maybe dually adapters with 4 paddles on the back.
