Adizero Distancestar 1 vs Endorphin Pro 5

The Adizero Distancestar is a track distance spike built to cover everything from the 1500m up to the 10,000m, which makes it one of the more versatile racing spikes you can buy. It sits below the specialist end of the Adizero range, so if you want a single spike for a whole season of track efforts rather than one event, this is the honest pick. A glassfibre plate underfoot gives you a firm, snappy platform without the aggressive geometry of a pure middle distance spike, so it stays comfortable across longer reps. At £90 it is one of the more accessible spikes on the market, which matters if you are a club runner buying your own kit. If you want something sharper for pure 1500m to 3000m work, the Adizero Avanti is the more aggressive sibling. For most distance track athletes, though, the Distancestar does the lot.

The Endorphin Pro 5 is Saucony's carbon marathon racer, and the fifth version is the most complete one yet. This is a road racing shoe built around a slotted carbon SpeedRoll plate sitting in a stack of PWRRUN PB and Super Critical foam, so you get that firm, rockered snap through toe-off that the Endorphin line has always chased. At £225 it lands squarely in the super-shoe bracket alongside the Nike Vaporfly 4 and adidas Adios Pro, and it earns the price if you are racing anything from 10k to a marathon. Compared with the Endorphin Pro 4 it feels a touch more planted and a little more forgiving on tired legs, without losing the rolling geometry that makes it want to move at pace. In our view this is a proper PB tool, not an everyday cruiser. Buy it to race, and it delivers.
