Adidas Adizero Prime X3 St Solar Blue

Solar blue gives the Prime X3 St a brighter, more obviously athletic look than the standard blue, with the colour carried across the upper and into the midsole sidewall. The engineered upper is smoother than the Strung version and wraps the foot closely, which some runners prefer over woven fibres on very long efforts in warm weather.

Everything that makes the Prime X3 platform useful is here: a tall Lightstrike Pro midsole for deep cushioning, Energyrods to keep that foam organised, and a broad base so the height does not make the shoe feel tippy. It sits outside race legal stack limits, which is the point. Buy it to train in, and pair it with something lighter for race day.

Good to know

• Runs true to size; the forefoot is roomy, so narrow feet can stay at their usual length.
