These rollerskis have only been used inside.
The rollerski is Marwe 620XC:
The 620 XC Roller Ski from Marwe is a redesign of their all time best skate style roller ski. It features great vibration dampening and a stiffness of the frame that put together provides the rider with a feeling of skiing on fresh snow. Furthermore it helps to keep the skier from getting numb and tired which help extend training sessions.
The wheels are made with Marwe's unique urethane compound that has excellent wet grip properties.
The Binding is the Rotterfella Xcelerator and fits NNN Boots.
