I bought a pair of Adidas Supernova Glides. They have the Boost foam with a little bit of the Eva foam as the midsole. My previous pair of running shoes was the Adidas Boost (now they have Boost 2). I had 2 pairs of those styles. I tried the Glides hoping for a little more stability in the shoe than the Boost. I also thought it the upper would be a roomie fit in the toebox than the techfit that the Boost utilizes. After having 2 runs totaling 12 miles in the Glides, I am ready to give my initial impressions.
I ran the heck out of my Yellow Boosts. I broke a lot of the old training rules. I quit rotating shoes every run, I used them to walk in for long days on my feet, etc. The midsoles were amazing. In fact my oldest pair of Boosts, still has a midsole as responsive as the Boost Foam in my Glides that are 2 days old. The Boosts have a techfit upper that feels like a s sock when you put it on. When I first put them on The shoes were lighter than the Asics I had previously run in, and the felt like I could immediately run a 20 mile workout. There was no “breaking in” period. The foam was reputed to send a lot of the pounding your feet take from the pavement back to the pavement keeping your legs and feet fresher. I found that my legs felt fresher during long runs, and I felt like I could run faster. Later, I had several good races in both pairs of Boosts. I set PRs in my 5K, 10K, and marathon. Adidas claimed runners would significantly reduce their times.
I was sold on the Boost shoes immediately after my first long run. I raced down hills really pounding the pavement. After that run, my knees and ankles didn’t have that ache I had become accustomed to when running hills. I finished my hilly long run and didn’t feel like I needed to take an ice bath and some Advil. It was liberating. I like ice baths. They are one of the best ways to recover from running. The only bad thing about an ice bath is the anticipation of sitting in the tub. You know what you are getting ready to do. You know it will help recover. You know the first 30 seconds are usually accompanied with very high pitched squeals. Very high pitched. But I didn’t need the ice bath. After a light stretch, water, and a snack, I felt like I could go out and run again. The Boosts wear through the rubber sole and upper, long before the Boost foam
My assessment of the Glides is positive with reservations. They are almost as comfortable as the Boost. They are light and easy to run in. You can feel the boost midsole in the ball of the foot very easily. The EVA stabilizes the transition between foot strike to push off, bit that’s the point the shoe isn’t as good for me as the Boost. I’m a heel striker—I know the barefoot and Vibram runners are going to suggest changing my strike to mid-foot, but that doesn’t work as well for me. The glides stabilize the heel strike, but are working against me. I’m sure a lot of it is retraining muscles and stabilizers, but I don’t feel the EVA is correcting me to a better ride. If I had a little more of a mid-foot strike, I think I wouldn’t notice the difference. Some people have issues with the Boost’s lack of stabilizers and would find the Glides really fit them well. The EVA foam is not a deal breaker. The upper is a nice change from the Boosts. The Glide has a more structured upper with a roomy toe box. The shoes fit snugly, but they don’t have the socklike fit.
I like the Glides. They are not a bad shoe. I think they will be better as I run in them more. I don’t feel the confidence in the shoe that I had for the Boost. They have similarities that will make them synonymous for some runners. They were $30 dollars cheaper than the Boost. I ran the Iroquois loop in the Glides and found them to be comfortable up and downhill. If I was purchasing again, I would make these my second set of shoes for short runs and rain.
Conclusion: Both are good shoes. I prefer the Boost.
