Price was more affordable to purchase from Amazon than Zappos, so you may want to consider next time. I do tremendous amount of lateral moves, martial arts, and cross fit training. These shoes are very stable, and include extra cushion for ankle stability. Using custom inserts may be a challenge, but Asics provide a good inserts. It is not super light, but adequate for extreme training. I am very impressed with engineering/design/material/and technology these pair offer. After wearing these, it will be very hard to walk away from Asics brand.
