Our Verdict
HOKA Skyflow
HOKA Bondi 9
The HOKA Bondi 9 is a better running shoe than the HOKA Skyflow if you prioritize cushioning for easy miles and longer runs. Its deeper cushioning provides better protection from road impact, while its superior energy return offers more assistance through each stride. Both shoes provide decent stability, but the Skyflow is lighter and has a lower heel-to-toe drop, giving it a less heel-biased ride.
