Choose the right running shoes

The shoe is the runner's only real piece of equipment — and a poor choice can quickly lead to injury. Here are the criteria that really matter, without the marketing.

First: usage

A daily training shoe (comfortable, durable), a fast workout shoe (more dynamic) and a trail shoe (grip, protection) are not chosen the same way. Start by defining what you run for before comparing models.

Cushioning: not too much, not too little

Lots of cushioning reassures beginners and protects on high volumes, but excessive cushioning can reduce feel. The right level depends on your weight, your weekly mileage and your personal feel. The most important thing remains immediate comfort when trying on: a shoe doesn't really "break in".

The drop

The drop (height difference between heel and forefoot) influences how much your calves and Achilles tendon work. Drastically changing your drop is a frequent cause of injury — see our dedicated article on drop and Achilles tendinitis.

Size: go large

Take half a size to a full size larger than your street shoes: your foot swells during effort. An inch of space in front of your big toe prevents black nails and blisters, especially on long distances.

Do you need a gait analysis?

Useful for reassurance, but not essential. The evidence that "correcting" pronation prevents injuries is weak. Your best guide remains comfort and reasonable progression in volume.

Replacing your shoes

Count 600 to 900 km depending on the model and your weight. Alternating two pairs extends their lifespan and varies the stress.

Once properly shod: progress

Equipment helps, but it's training that makes you run faster and longer. Sports Coach AI builds your progression based on your data, controlling load to prevent injuries.
