For a long time balancing lightweight uphill performance with a powerful downhill feel was a bit of a myth, but then boots like the K2 Dispatch Pro Ski Boot came along and proved everyone wrong. The balanced performance of these boots starts with the Pebax construction that sheds weight but remains rigid and continues through the Powerlock 2. 0 walk mechanism that stays where we set it. Finally, the 2-piece, 4-buckle design offers a familiar downhill feel without limiting uphill performance.
