This shoe is a speed day trainer that would work for tempos, intervals, and racing. For $160, you can get 300 to 325 miles of life out of it, which is a pretty appealing offer for someone who doesn't want to break the bank and spend $250 on the Vaporfly or $275 on the Alphafly for only 250 miles of use.

I used the Nike Zoom Fly 4 as my training shoe on most of the runs while training for the half marathon I ran in Ljubljana. I did a few easy runs in the shoe, a few tempo runs and 2 long runs, one of them a long run workout.

The broad flat tongue takes a little getting used to, but it gives enough protection from the laces without adding more padding or weight. I had no issues with hot spots, breathability, or sizing. Purchase your standard running shoe size. The Lunarlon midsole creates a platform that has you riding high.

It comes with their super responsive ZoomX foam and a carbon fibre plate. Created to close the gap between your weekend training and race day, the Zoom Fly 5 is meant to offer comfort and stability with a propulsive sensation to make you feel fast and fresh after your run.
