SISU OLX is the successor of SPIRIT OLX which was for many years one of the most popular racing studs in the ICEBUG range. The traditional lacing system has been replaced by the BOA® Fit System, which ensures a perfect fit and speeds up the on/off process. The BOA® Fit System also improves grip and midfoot support, which in turn leads to better running economy. A new feature is the very durable bluesign® upper, which is very pleasantly flexible on the foot, similar to the classic textile material. The lower cuff of the upper, made of soft TPU, which is double stitched for extra strength and durability, is therefore more versatile, suitable for runners with medium width feet. Thanks to the low drop (4mm) and the system of connection of the upper with the uncompromising sole, the shoe reads the terrain perfectly and is also amazingly maneuverable. You will appreciate its superior handling characteristics, especially in wet and rugged terrain. of course, the maximum non-absorption is a matter of course, which even in total wetness, absorbs only about 15-20% of water. The special Stitch-and-turn sewing technology is very resistant to the expansion of shoes in wet conditions. Ensures a firm and stable fit, and an unchanging shoe shape even in extreme and wet environments. The low profile and tight fit around the foot, provides the runner with excellent control, while allowing maximum adaptability and flexibility for natural movement. The recessed tines and their integrated diagonal layout ensure maximum traction on any surface.

Eco-friendly production of the upper and midsole, made from recycled material with Bluesign® certification
