Nike Lunarglide+ (what I'm currently running in)

Forget the gingko biloba. Cambridge University scientists have discovered that going for a run regularly leads to the growth of new cells in the area of the brain that boosts your memory. The researchers studied two groups of mice — one group had access to a running wheel while the the other group (the control group) didn’t. After a few days, they conducted memory tests with both groups and the runners were almost twice as successful at the tests than the control group.
