Upwards curvature means foot muscles do less work, potentially weakening them over time
They may feel comfy, but wearing shoes that curve up towards the front may be weakening your foot muscles and increasing your risk of injury.
This upwards curvature, known as a “toe spring”, is a common feature of many shoes, especially trainers. It helps the front part of the foot to roll forwards when walking or running, enhancing the comfort of thick and cushioned soles. But despite their ubiquity, the effect of toe springs on our foot muscles hadn’t been well studied, until now.
