Nike Savaleos review: We consider the Nike Savaleos a successful experiment of turning a high-heeled lifting shoe into a more versatile gym tool. Even though it loses some of its performance in the more niche activities, it is a truly unique crossover. We believe that entry-level gymgoers will benefit the most from the Savaleos. Its elevated heel mixed with a lightweight and flexible setup readily substitutes two pairs of trainers for the price of one.
