Since the first edition of the DynaFlyte launched in 2016 the aim of the shoe has been simple: to deliver the ideal balance of speed and cushioning to make it suitable for all kinds of running. In the years since the shoe has been refined and improved to make it lighter and more responsive, while still retaining enough cushioning and support to make it suitable for long runs. I tried a variety of runs in the DynaFlyte 3 and although it undoubtedly has strengths and weaknesses, it does work as an impressive all-rounder shoe that most neutral runners will find fits the bill for training of all types as well as racing.
Key to that is the FlyteFoam Lyte midsole, which provides enough cushioning to protect you from the impact of logging big distances while still being light enough not to be much of hindrance on fast, short efforts. I say not much of a hindrance, because the DynaFlyte 3 is not an out-and-out racer. Its 257g weight (men’s size 8) is lightweight for a daily trainer, but it’s not as explosively responsive or lightweight as a shoe like the Adidas Boston 7 or Nike Zoom Fly. I tried a track session and a tempo run in the DynaFlyte 3 and while it’s no slouch, these aren’t the shoe’s strongest area. There’s little pop off the toe and the hefty stack of cushioning at the back of the shoe is noticeable and a little cumbersome when sprinting.
However, the track isn’t really where the DynaFlyte 3 is designed to spend its time, and when you take it out for longer efforts on the road it shines. The ride has a firm feel that’s quite different to the raft of bouncy shoes that have followed the trail blazed by Adidas’s Boost foam, and while I do love running in a bouncy shoe, that difference is no bad thing. The FlyeFoam Lyte cushions the impact of running without you losing the feel for the ground. The heel-to-toe transition is smooth and when you get into a rhythm at a good pace over long runs, the DynaFlyte quickly disappears on the foot.
It’s a shoe that would work well for marathon and half marathons in particular, but it’s also comfortable to wear when you’re taking it easy over long distances.
The upper on the DynaFlyte 3 also impresses. The flexible Adapt Mesh 2.0 fabric stretches to accommodate the foot nicely without sacrificing too much support. Opt for the LiteShow version of the trainer and the fabric has reflective details woven throughout to make you more visible at night.
Advances in foam technology have resulted in a lot of brands making lightweight shoes that still carry a comfortable stack of cushioning to support you over long distances, and the DynaFlyte 3 is one of the best available on that front. If you’re looking for a running shoe to carry you through a lot of of training that’s also fast enough to help you impress over 22.1km or 42.2km come race day, it’s certainly a shoe to consider.
