Asics Gel-DS Sky Speed
Impressive. The Gel-DS Sky Speed is a very responsive (firm and fast-flexing), very lightweight training shoe. It's average to wider feet, and can double as a racing shoe for middle-of-the-pack runners (but is too heavy to be a sub-elite or elite racing shoe).
The DS Sky Speed is just as responsive as many of my racing flats, but provides more cushioning allowing for less fatigue and faster recovery times after tempo runs. It begs you to run fast.
These are not shoes for heel strikers. The heel unit is there for support but does not impede a midfoot-striker's stride, as is the case with shoes with thick heels. The midfoot and forefoot sections are also narrower than normal for ASICS, in my opinion, giving it a truly neutral platform. There is also plenty of real rubber on the outsole making this a trainer that will hold up to high mileage training, on- or off-road.
The Sky Speed provides a good snug that kept my foot locked in place, which is especially important on 20+ mile runs, and especially on long downhills.
The Sky Speed is not the lightest on the scale, but it makes up for that fact through providing an extremely responsive ride. I can even use it for longer tempo trainings whereas I typically use racing flats. I can’t consider it a racing shoe for myself, but for a trainer, it is very impressive.
This shoe is best suited to neutral runners and slight pronators. While Asics lists the shoe for mild pronators, I would say that anyone with more than a slight over-pronation would need a shoe with more support.
