Saucony Sinister review: what runners say
Fit
Narrow, spike-like fit with low volume. Runners with wide feet should avoid it; those with normal or narrow feet will find a precise lockdown. Half-size up recommended for anyone who struggles with low-volume lasts.
Feel
Natural, responsive ride courtesy of PowerRun PB on a low stack (25 mm heel, 19 mm forefoot). Plateless construction makes for a flexible shoe with a close-to-the-ground feel similar to a modern track flat.
Durability
Sources flag insufficient durability as a structural concern. No specific mileage noted; the thin chevron-pattern outsole suggests accelerated wear compared to higher-stack racing options.
Best for
Racing flat for 5K–10K road racing and track workouts. Suited to normal- or narrow-footed runners seeking extreme lightness (4.9 oz) and a close-to-the-ground ride. Not recommended for longer distances without adequate preparation.
Weak points
Short lifespan cited as the primary drawback. Some sources note that the low stack penalizes distances beyond 10K; lateral grip unreliable on a wet track.
