Runners are always looking for an advantage to shave some time off their runs.  Parked in the obvious garage is a new report that confirms lighter weight shoes do really help you run faster.  Scientists at the University of Colorado recruited runners for a 2 mile run once a week for three weeks.  Unbeknownst to the runners, small lead pellets were sewn into two of the three pairs of shoes used adding about 3.5 ounces of weight per pair of shoes.  After tracking the time it took the runners to complete the course, they were able to confirm that the additional weight slowed the runners down about 1% per 3.5 ounces. Don’t go out and buy a new pair of running shoes just yet, though. The researchers note that lighter shoes won’t necessarily make a runner faster. The team’s previous research has shown that proper cushioning also reduces the energy cost of running—so swapping out foam or other padding for a super-streamlined design could potentially backfire.
