Foot and Pylon (photo: B1, B2)
-
Dan rides the Freedom Innovations Silhouette® foot. Foot and pylon are one piece and made from Carbon fiber. This foot provides smooth rollover during edge to edge transfer and good stability for riding. It is a moderate to high activity foot and mimics ankle flex which helps weight the toe-side edge consistently through the turn. There is little torsional twist in ankle but it is less than the Ossur Ceterus®. Dan, unlike some other riders, prefers to have a little twist in the pylon.
-
The standard pyramid system at the top of the pylon is set to a regular walking alignment. The connection between the female end of the pyramid and the carbon pylon are epoxied to stop lateral twisting in the connection. The force from snowboarding is too great and this extra measure will help prevent injury when it comes loose during riding.

Socket (photo: C1, C2, C3, C4, C5)

The socket has a pin and and valve suction system are designed by Coyote Designs™. He uses the pin system and one-way suction valve for everyday activity, but when snowboarding he uses a suction sleeve to keep leg tight to the residual limb. The combination of these three suspension devices is adequate for high activity riders. Please note: most riders are using a pin and suction sleeve combination.

Dan and his prosthetist have come up with a clever socket design that help provide Dan with extra knee support. The socket extends higher than a conventional socket and has a coke bottle curve around the sides of the knee. This extra feature helps prevent torsional twisting while riding and protects the knee from injury.

Pylon Sheath (photo: D1, D2)
-
Shaped medium weight foam sheathed in duct tape and shaped like shin. This fills in the gap between boot and pylon and prevents a sloppy fit. But one needs a little play in sheath for proper body/board response so he uses a medium weight foam. Soft foam gets packed out quickly and hard foam doesn’t give enough. Cosmetic foam covers serve the same purpose.
