Adidas Energy Boost 2 Review

The Adidas Energy Boost.

Adidas Energy Boost. The foam used in this shoe looks a little like Styrofoam/polystyrene, but it's actually remarkably tough to cut. You can also see a small indent in the top of the midsole where the foot pod would go.

The Adidas Energy Boost 2 has a new material in the midsole (see 'Adidas Boost Foam' below) which changes how this shoe feels. The Boost does not really count as a minimalist shoe or a Minimax shoe, as it has a mainstream design, with the typical raised heel and cushioning that is no thicker than normal. However, because the boost foam works so well, it works far better than you'd expect.

• As a Minimax. Though it's not as thick as a Minimax shoe, it's soft cushioning makes it feel much thicker than it actually is, and it's a lot softer than something like the Brooks Transcend. While it does not offer the protection of a Hoka, it does offer a lot of the feeling of soft cushioning.
• As a minimalist. If you take out the insole, you also lose quite a bit of the higher heel and have something that's close to a minimalist shoe. I estimate that the insole is about 3mm in the forefoot and 5mm at the heel. Without that extra, the shoe is a 7mm drop (14mm/21mm). The shoe is light weight, and the new foam is pleasant under foot, combining a forefoot that had good ground feel with reasonable protection.

The Energy Boost is immediately comfortable, with a light, flexible upper with no noticeable seams. I'm thankfully Adidas has used a traditional tongue and laces, rather than a sock style upper or Velcro fastening. And while the sole has the traditional raised heel, there is none of the multi-density foam or other intrusions that are so common. I think a lot of people will buy the boost because of its immediate comfort, but stay with it for its extraordinary characteristics.

1 Adidas Boost Foam

The Adidas boost uses a new type of foam in the sole that has more bounce and is more resilient. Adidas demonstrates this extra bounce by dropping a steel ball on their new foam and EVA, the industry standard foam. Because of the extra energy return in their new foam the ball will bounce much higher than on EVA. However, when we run our feet do not bounce off the ground, but have a short period of sustained contact, often called the 'stance phase'. So when your foot lands, it seems that the boost foam would return the landing shock back up your leg rather than absorbing it, which is less than ideal. It would be good to see a study that looks at how the boost foam changes the stresses on knees and hips compared with a standard running shoe. Regardless of how the bounce impacts your running, the increased lifespan of the new foam is appealing. Having a shoe that lasts longer is obviously good, but Adidas also claim that the new foam is more consistent through most of its lifespan, rather than gradually decaying in the way EVA does. Adidas also claims that their new foam does not change characteristics in extreme temperatures like EVA does.

2 A Comparison with other Recommended Shoes

If you're looking for "the best of the best" running shoe, here are my top picks. Of course, the answer will depend a little on what you're looking for, so I have recommendations for various categories. Best All Round Shoe. The Altra Escalante is my current all-round favorite. It has plenty of cushioning for its weight, it has a very springy midsole, it lasts well, and it has a shape that's closer to the shape of a human foot than most shoes. It's a great shoe for any runner, including those Starting to run. It's also a fairly easy shoe to find due to its popularity. Best Maximalist Shoe: If you want something massively cushioned, then I'd recommend the Saucony Kinvara 8. It's remarkably light and remarkably cushioned, beating Hoka at their own game. Best Optimal Shoe: For those looking to trade cushioning for speed, the Nike Zoom Streak LT 3 was my top pick, but the latest version (LT 4) falls short of it's predecessor. There are lots of great optimal running shoes, which provide just enough cushioning with light weight and minimal frills, but all have their weak spots. Probably the best option at the moment is the Altra Vanish-R, which offers great cushioning for just over 5oz/150g. Fastest Shoe: If you really want speed, then check out the Nike Vaporfly 4%. It's light, massively cushioned, and has a carbon fiber plate. Nothing comes close, not even the now defunct New Balance RC5000‏‎ or New Balance RC5000v2‏‎. There are a number of caveats; it's really expensive, it's really hard to find, and there's a significant injury risk. Best Minimalist Shoe: Merrell Trail Glove. I recommend the trail glove for road running in spite of the 'trail' moniker. It's not a fast shoe by any means, but it's comfortable and will last well. All Terrain Shoe. For trail running, I've become a fan of Altra, and I think their best shoe is the the Altra Timp, though the Altra Lone Peak is really close. Honorable Mention: It's not really a running shoe, but the Vivobarefoot Ra is comfortable, minimalist and can more or less pass as a dress shoe. I've worn mine to weddings with a suit and they've not looked out of place. You can run in the Ra, but the leather means it doesn't breathe well.
