The Rocket X 3 is Hoka's do-it-all carbon racing shoe, the leaner, cheaper stablemate to the maximal Cielo X1. Where the Cielo goes big on stack and cushioning, the Rocket X 3 keeps things sharp: a PEBA midsole, a full carbon plate and a 40mm heel that stays legal for racing. At 210g it is not the lightest super shoe on the shelf, but it is versatile in a way the pure marathon rockets are not. This is a race shoe you can genuinely run across distances, from a 5K where you want turnover to a marathon where you want protection late on. We rate it as the sensible carbon racer for runners who want one fast shoe to cover everything rather than a shelf of specialists. At an RRP of 239 pounds it is priced with the elite pack, so you are paying for that flexibility.
Most carbon racers ask for a steady foot. Saucony built the Endorphin Pro 5 for runners who find them a bit wobbly. It's a carbon racing shoe with a slotted plate and PWRRUN PB foam, and at a listed 206g it isn't among the lightest super shoes. In return you get a planted, guided ride. Reviewers rate it most highly between 5K and half marathon pace, and plenty of club runners will happily take it through a marathon. Fordy Runs sees it as a race shoe for everyday runners rather than elites. Believe in the Run was cooler: it found the shoe barely changed from the Endorphin Pro 4 and missing the pop of the best race shoes. The two views don't really clash. If you want Saucony's most aggressive racer, that's the Endorphin Elite 3. If you'd rather have a stable, hard-wearing race shoe you can also train in, the Pro 5 is one of the easier ones to get along with.
Putting two running shoes side by side shows the trade-offs quickly, but which one suits you still depends on how you run. Weight and stack height set the feel underfoot. A lighter shoe with a lower stack feels quick and nimble, and a heavier shoe with a taller stack gives a softer, more protective ride over long miles. Drop matters too: the lower the heel-to-toe drop, the more work your calves and Achilles do.
Prices come from the UK retailers we check every day. Best price now is the cheapest current price we can link you to. The 90-day low shows how cheap the shoe has been lately, and the 30-day average tells you whether today's price is a real drop or just what it usually sells for. If neither shoe is at a price you like yet, open its page and set a price alert. We'll email you when it falls.
