Salomon's advice is to fit by space and feel rather than assuming your street size carries over. Aim for about a thumb's width — roughly 1cm — between your longest toe and the end of the shoe; that's what prevents bruised toes and black toenails on long descents.

Then check the back: your heel should be locked in and shouldn't slip. Feet swell on long runs and in heat, so try shoes on at the end of the day, in the socks you'll actually run in.

• Trace and measure your foot, then check it against Salomon's size chart rather than guessing.
• Your heel should not lift or slip when you walk.
• Salomon shoes are designed to run straight out of the box — a shoe that pinches in-store won't improve with wear.
