NILS Extreme 4-in-1 are universal skates for beginners and intermediate users that can be easily converted from inline to ice skates thanks to the interchangeable blade. They offer 4-level size adjustment, an aluminium frame, ABEC 7 bearings and a comfortable inner boot for stable and agile skating.

4-in-1 conversion to inline and ice skates
The skates allow quick changes of use thanks to the interchangeable ice blade. The package also includes screws and washers for converting the frame into 2+1 and 2+2 configurations.

Adjustable size by up to 4 levels
The outer boot can be adjusted to four sizes by pressing a button, making it easy to adapt to current needs and allowing it to “grow” with a child’s foot.

Aluminium frame, ABEC 7 and comfortable boot
The aluminium rail combined with soft PU wheels and ABEC 7 bearings supports smooth and agile skating. Comfort is provided by the inner boot made of suede, MESH, EVA and high-density foam, complemented by ventilation at the toe.
NILS Extreme 4-in-1 skates are an excellent choice for children and teenagers who want to use one pair of skates in different seasons. Thanks to the option of replacing the frame with ice blades made of stainless steel with a high carbon content, they can be quickly adapted for winter and summer.
The outer boot is adjustable to four sizes by pressing a button, so it can also serve as a “growing” boot. Comfort is provided by the inner boot made from a combination of suede, MESH fabric, EVA and high-density foam. Ventilation openings at the toe improve breathability.
