How to choose running shoes
There is no single best running shoe. The best one is the one that fits your foot and feels comfortable after the first kilometre.
Fit first
Leave about a thumb's width in front of your longest toe. Your heel should not slip, and the widest part of your foot should not press against the sides.
Cushioning
More cushioning feels softer on long runs and for heavier runners. Less cushioning feels faster and gives more feedback. Most runners do well with something in the middle for daily training.
Drop
Drop is the height difference between heel and forefoot. If you are not sure, stay close to what you run in now and change gradually.
When to replace
Most shoes last 600–800 km. If the midsole feels flat or you start getting new aches, it is time for a new pair.
