The Mach X 3 is Hoka's do-it-all super trainer, the shoe you reach for when one pair has to cover the tempo session on Tuesday and the long run at the weekend. A Pebax plate sits inside a tall 44mm heel and 39mm forefoot stack, so you get a snappy, rolling ride without the harsh, race-only feel of a full carbon racing shoe. At 289g it is not light for the category, and you notice that on genuinely fast reps. What you get in return is versatility. It has enough cushioning to protect your legs over 20 miles and enough pop to hold marathon pace when you ask for it. Think of it as a workhorse with an extra gear rather than a pure speed tool. For runners who want a single plated trainer that does most jobs well, and who do not want to spend race-shoe money doing it, we rate the Mach X 3 highly. Just go in knowing it prioritises range over outright speed.
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.
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.
