My verdicts
Adidas
Adizero SL2
If you want one shoe for all your training and racing from 5 km to the half marathon, the Adizero SL2 is highly recommended at ₹7,000 to ₹8,000. I would not buy it at the ₹12,000 retail price.
Avoid if: Avoid it if you are a heel striker, run very slowly, or need stability or ankle support.

Pureboost 5
The Pureboost 5 is one of the best daily trainers you can get under ₹6,000, with balanced, bouncy Light Boost that stays fun even at slow paces. Grab it under ₹6,000; it is not worth the ₹12,000 retail price.
Avoid if: Avoid it at the ₹12,000 retail price, or if you need full cushioning beyond about 18 km at slow paces.
