adidas’s own £450 question: what does doubling the price and halving the competitive life actually buy?
The adidas Adizero Adios Pro Evo 2 is 63g lighter (138g against 201g), the adidas Adizero Adios Pro 4 is £230 cheaper at RRP (£220 against £450), and the adidas Adizero Adios Pro 4 stays fast for roughly 140km longer (~260km against ~120km). Both are inside the World Athletics 40mm road limit.

Reference times, trainer baseline, whole-life economics. Your own time changes the answer — use the reading above.
The lightest marathon shoe ever sold and, on the evidence, the fastest. At 138g it is closer to a track spike than a road shoe.
■ Caution The reason it is on this list twice over: at £450 with a competitive life around 120km, this is comfortably the most expensive shoe per race you can buy. Run the numbers before you buy — that is what the calculator is for.
The best value at the very top of the market. Within touching distance of the Evo 2 for performance at half the price and twice the life.
■ Caution The EnergyRods give a distinctive rolling feel that some runners never get on with. Try before you commit if you can.
