Absolutely make you faster, especially if you're a heel striker. Long learning curve, though, and don't push yourself too far too fast.

Long battery life, looks as good as a headlamp can.

Comfortable with durable soles, but the uppers wear and break pretty easily

Great idea and good execution. Some chafing is possible from the seams, but the physical separation really works.

Good. lightweight bottle carrier, some issues with slippage when wet, but overall a good value

Interesting solution to night time running. Comfortable for most, but occupies your hands.
