Watch Daryn Robles on you tube (plenty of them) and he’s one of the best in shortening the stride or ‘cut stepping’. The rotation of the leg (leg recovery) is less, knee lift is less. So you can try to learn that by using smaller hurdles and bringing it closer. But you need to be a fast sprinter and a tall hurdler to have the need to do that to the extent the elite hurdlers do. So i am assuming that you are just overstridinig between the hurdles and probably need to fix it in flat sprinting.
