RACE READY 87/100

THINK FAST The new Vazee Prism marks itself out as a fast-run specialist; testers noted it feels lighter than previous NB offerings. This racing model might not come with go-faster stripes, but it will serve you well with a 10K PB on the line. EXPERT VERDICT The midsole remained bouncy and durable, even when given a pounding by heavier runners, and flexibility is excellent. Be warned – the toebox is a tad narrow. Maybe stick a precautionary plaster on your pinkies.
