The New Balance Rebel v4 and Saucony Endorphin Speed 4 are two of the top new speed training options for 2024. However, the shoes serve two different takes on speed—the Rebel v4 is light, low and lean, while the Speed 4 has a taller stack, full race day foam and a plastic plate. In this video, I put the two to the test in a marathon pace fartlekstyle workout so we can see how they match up in the real world. Here's how they fared out there on the run.
