There is a lot that you can do for a faster tempo. You can try interval training, stretching, fartlek or simply take very light running shoes. Adidas SL20 is a great example of lightweight running shoes that comes in at only around 220 grams (7.76 oz). With this model you will get boosted on speed and achieve your target faster than with most other running shoes.
As for weight, Adidas SL20 is very comparable to Nike Zoom Pegasus Turbo 2, Saucony Guide 13, Nike Free RN Flyknit 2018 or less known ON Cloudswift. I am mentioning these models because I had them on my trainings and this model of Adidas SL20 comes out the best. It offers a completely new midsole, called Lightstrike. From the name, as you may guess, it is super light.
The weaker point of the midsole is the cushioning itself as it is quite firm. So don’t expect a great performance from this running shoe on longer distances. The midsole is not as cushioned and returning energy as in the case of Adidas Ultraboost 20. That one performs well for long runs, it is more protective for your knees while Adidas SL 20 is lighter. So for shorter distances and fast-tempo runs, it’s the one that you should pick!
The one-piece mesh upper perfectly balances the lightness of the shoe and makes it a great running model somewhere between a minimalist running shoe and unrealistically padded, highly-volume model. Heel-to-toe drop is 10 mm, so you cannot say this is a minimalist running shoe at all. I felt it was a good balance for every run, up to 10 km. The laces, though, could be shorter. They unleashed quite often, so I would definitely consider this to be a disadvantage of the shoe. Hopefully, Adidas will make some changes until the next model release.
Except for the unleashing shoelaces, I found Adidas SL 20 to be a fast, high quality model, perfectly working for shorter runs and other workouts. The durability was fine so even taking it to a bit difficult terrain or on unpaved paths, it served even after 100 km without changes. Overall, it’s a great running shoe.
