Magic Speed 5 vs Endorphin Speed 5

The Magic Speed 5 is Asics doing the sensible thing: a carbon-plated running shoe that hands you race-day pop without asking for full super-shoe money. It sits a rung below the Metaspeed Sky racers, so think of it as a carbon tempo shoe and part-time marathon shoe rather than an out-and-out record chaser. At 193g with a 37mm heel and a 7mm drop, it is light and low-slung enough to feel fast, and the FF Turbo foam gives it genuine bounce when you lean into a session. What makes it worth a look is versatility. It will pace a threshold workout on Tuesday, then carry you through a half or a first marathon on Sunday without feeling like overkill. It is not the softest or the most aggressive shoe in its class, but as a one-shoe answer for a runner who wants some carbon assistance across a range of paces, we rate it highly.

The Endorphin Speed 5 is Saucony's do-it-all tempo trainer, and in our view it is one of the most useful running shoes you can own. It sits below the carbon race shoes and above the plush daily trainers: a springy, nylon-plated shoe built for the fast half of your week. At 155 pounds it costs less than a carbon racer, and the nylon plate means it flexes rather than dictating your stride, so it stays friendly across a range of paces. Push into a tempo and the PWRRUN PB foam gives you real bounce and rebound. Slow it down for a steady long run and it still feels smooth and protective. Plenty of runners will race a half or even a marathon in it. If you want one lightweight shoe to cover workouts, tempo days, progression runs and the odd race, this is the running shoe we would point you to first. The nearest rival is the adidas Adizero Boston 13.
