Shortening your stride and landing closer to your forefoot, as opposed to heel-striking, reduces the chance of some injuries, but increases the chance of others. This was the finding of a recent survey of 320 novice runners.
The results found that injuries such as plantar fasciitis were almost non-existent in the forefoot group, while lower leg injuries such as Achilles tendinitis were more common. This table lists the injuries over one year among 166 runners who ran more on their forefoot and 154 who did not:
The researchers concluded that those who ran more on their forefoot had a 62% lower injury risk than those who didn’t.
