Superblast 3 vs Endorphin Speed 5

The Superblast 3 is the softest, bounciest Superblast yet, with a top layer of FF Leap over FF Blast Plus. On paper that means plenty of cushioning for not much weight, at 235g with no plate, and Ben Parkes says it may be the most comfortable long-run shoe they've worn.

What you give up is steadiness. Several reviewers found it wobblier on corners and as their legs tired, and one UK reviewer who preferred the firmer Superblast 2 now sends people to the Megablast instead. Most reviews still rank the Superblast 3 among the best super trainers you can buy, and one lab rated its grip the best it had tested.

We'd pick it as a marathon-training and long-run shoe for neutral runners who want a soft, lively ride. If you like a firm, planted shoe, it probably isn't for you. At £200 RRP it's one of the dearest trainers Asics makes, so check the price table before you buy.

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.
