Positive450 miles across easy runs, threshold work, track sessions and longer efforts, plus a track workout at the end to see if it was still fast. The foam has lost some bounce and the plate feels a little more flexible, but it handled 6-minute mile pace and a fast 200 m without trouble. The upper and lockdown held up well, while wet-surface grip is weak and worsened with mileage. They would still buy it as a lasting do-it-all trainer.

MixedKept for speedy days only; the forefoot feels a bit stiff at easy paces and on long runs.

PositiveAfter a 19 km first run, the Endorphin Speed 5 is their favourite since the ES2: snug light upper, fairly firm but cushioned snappy midsole that likes to pick up the pace and doesn't feel heavier despite the weight gain.

PositiveQuick turnover, efficient, and a breathable, comfortable upper. The ride harks back to her favourite v2/v3. Another tester finds it on the firm side, without as much bounce or energy return as he'd like.

PositiveA solid choice for uptempo runs and even daily training. Small updates make it feel more dialed-in for speed, and fans of v4 should be pleased.

PositiveA great, very versatile all-rounder or workout shoe. However, it isn't a noteworthy upgrade on the Speed 4, which is now heavily discounted and the better buy.
