>>83829 That's exactly what Vibrams are for. It protects your feet from glass, etc. without being overly bulky.
>>83831 I run 5k's with moderate frequency. I don't do marathons. The only way to win one of those things is to not run.

>Rearfoot strike was observed in 74.9% of all analyzed runners, MFS in 23.7%, and FFS in 1.4%. The percentage of MFS was higher in the faster runners group, when all runners were ranked and divided into 50 runner groups at the 15.0-km point of the competition. In the top 50, which included up to the 69th place runner in actual order who passed the 15-km point at 45 minutes, 53 second (this speed represents 5.45 m x s(-1), or 15 minutes, 17 seconds per 5 km), RFS, MFS, and FFS were 62.0, 36.0, and 2.0%, respectively.
>The findings of this study indicate that foot strike patterns are related to running speed. The percentage of RFS increases with the decreasing of the running speed; conversely, the percentage of MFS increases as the running speed increases. A shorter contact time and a higher frequency of inversion at the foot contact might contribute to higher running economy.
They don't specify what the difference between forefoot and midfoot is though. I've heard forefoot be referred to as the toes before, and midfoot as the ball of your foot. Either way, it's not heelstriking.
