Review summary
Written by Augur from the 23 reviews analyzed
This road running shoe immediately stands out for its remarkable step-in comfort and highly pleasant running feel. Its high-performance cushioning is paired with excellent responsiveness, making it particularly versatile for varying speeds and training distances.… Its design offers neutral stability and good grip, although the specific Flex-design outsole tends to trap small stones during runs.
