The design team worked on a new asymmetrical midsole design. Two hollowed-out areas on the outside and a flattened structure on the inside improve stability and rotational control , supported by a less concave area from the inside of the heel to the medial side. The shallow 5 mm drop and the refined design of the upper make it the perfect companion for long runs and daily training. The top of the tongue has been redesigned and secured laterally with an elastic mesh integrated into the lining construction to prevent twisting and ensure a secure fit without sacrificing flexibility . The heel has been widened by 9 mm, the midfoot by 13 mm, and the forefoot by 5 mm. The length of the sole on the medial side of the heel has been increased from 6 cm to 11 cm, resulting in improved rotational control.
