Attiva Catches
The materials used for the HotForm liner offer a defined, high performance fit. A soft outside ethafoam, and a dense premolded padding combined with sensor padding and a velvet lining all contribute to the performance of the HotForm liner. The Hot Form liners offer customized fit with minimum time and effort. The liners are heated utilizing a special transformer. Hot Form is the only system to heat the moldable materials from the inside out. The result is complete molding of the liner to the foot and of the liner to the shell for a true customized fit.

Home Adapter
A home adapter can be purchased.
After a day of skiing, the boots can be plugged in to warm and dry the liners. (The voltage of the home adapter is not sufficient to re-mold the liners. Only the in- store transformer has sufficient voltage to heat the liners enough to re-mold them.)

Car Adapter
A car adapter can be purchased that plugs into the car lighter. The boots can be brought up to body temperature on the way to the mountain. (As with the home adapter, the liners cannot be re-molded with the car adapter. Only the transformer will heat the liners enough to be re-molded.)
