The Adidas Retropy E5 Boost is a 1970s running-inspired trainer made of different premium materials which are easy to style with any look with a heel-to-toe boost midsole. 

The E5 Boost upper blends designs from the Adidas Racing 1 and other trainers in the German giant’s archives. 

What is Adidas energy boost midsole?

Adidas Boost is a blend of small visible pellet balls which are squashed and put together into a foam. They store and free endless energy every time your foot hits the ground for mega comfort. 


How does the Retropy E5 Boost fit?

The Retropy E5 Boost Trainer fits true to size and is more suited for narrow feet. If you have narrow feet this is the perfect sneaker, go for your normal size. 

Reason To Cop:Annoying Things: 
The toe area is roomy. Stiff material on the dimple tongue may cut into the ankle. 
Under £100. Support and feel may not last due to the soft materials. 
Super squishy, comfier than ultraboost for everyday use: feels nice. Only really look good if you have narrow feet. 
Nice arch support. The tongue could be a bit squeaky when walking, not a major issue. 

To make sure the Retropy E5 Boost fits, the widest width of your foot needs to fit inside the shoe without being too tight. Going up a size will cause heel slippage

What to do if you have two different size feet?

Having different-sized feet is normal and if the difference in size is small you should:

  • The Retropy E5 Boost isn’t really for wide or flat feet the Adidas ZX 5K Boost is a better option. 
  • Wear thinner or thicker socks depending on the difference in size. 
  • Losen laces if the shoes become tight. 
  • Remove an insole for the slightly larger foot.

Which socks to wear with the Retropy E5 Boost shoe?

Recommend wearing thick crew or mid-ankle sports socks, as the dimple tongue design may cut into your skin. 

Can you wear Retropy E5 for running? 

No, wouldn’t advise you this there are better running shoes on the market. The Retropy E5 Boost Trainer is a soft 70s running culture-inspired everyday shoe. It’s made for low-impact activities like walking. 


Is the Retropy E5 Boost good for wide feet?

  • Better suited for narrow feet but the lightweight material on the upper flexs so could get away with it.
  • The ball of the feet should sit comfortably at the widest part of the shoe without sticking out too much. 
  • Sneakers should feel comfortable on the foot not tight or loose.
  • For tight fit, go one size down.
  • For a loose fit, go one size up.

Editors Thoughts:  

  • Some firmness in the boost midsole for stability and foot massage feeling, feel connected to the ground.
  • Adidas claims it’s suede, but feels more like nubuck tbh. It’s mad soft but deforms pretty quickly. The sole goes really thin at the from so it feels like your foot is sliding down a slope. 
  • Retropy E5 reminds me of the New Balance 327. Chunky, versatile, and super comfortable.
