Shorttrack (fingertips) caps are easy to glue on the glove. When the left hand hits the ice during the high speeds reached during the short track, these caps provide less friction. Due to the smooth structure of the caps, the glove glides over the ice, as it were.
As a result, they also provide extra stability and that the speed is maintained.
Tip: just use simple instant glue to assemble these fingertips.
