A second iteration to the loved SL20, the Adidas SL20.2 hits the right balance between comfort and style that it can be your trusty and fashion-forward daily trainer.

Adidas SL20.2 vs. SL20: What are the updates? 

Here are some of the changes incurred by the SL20 on its second iteration: 

Heavier. The original Adidas SL20 weighs in at 8 oz while the SL20.2 weighs 8.7 oz. 

Lower drop. This allows for a lot more ground feel for a better response. Prior to this iteration, which has a 9.5-mm drop, the SL20 features a 10-mm drop. 

Better lockdown. All owed to the new, dual-layer mesh upper of the running shoe, a snug wrap is delivered for a stable performance. 

What is it for? 

  • 5k runs
  • speed runs
  • middle-distance runs 
  • daily training (if you're amenable to a less cushy midsole than typical trainers) 

When not to use it 

Since it's designed to up your pace, it's simply not perfect for: 

  • Long, mellow runs 

Given such a case, another great option from Adidas would be the Ultraboost.
