I run 30-60min @ 6:15/mi miles, 10-30min @ 5:45/mi, and the occasional 5min @ 5:00/mi.
My Brooks PureConnect 4s lack the toe-off, and my Vazee Paces lack a smooth transition. Plus both are a bit heavy for me.
Thinking about getting Saucony Kinvaras. Any other (cheaper) options? I'm a poor college student.
