Makes me faster!

The Megablast is a lightweight, springy shoe that actually made me faster, especially down hills. The shoes spring me forward. Definitely the best running shoes I’ve ever had.

Mega uncomfortable

The fit was a problem for my wider, higher volume feet. It’s made for runners with narrow feet.

Great Daily Trainer for Easy Runs and Tempo Workouts

I’ve been using the ASICS Megablast mainly for easy runs, tempo workouts, and occasional gym sessions. The cushioning feels soft and comfortable while still providing enough responsiveness when I pick up the pace during tempo runs. The ride is smooth, and the shoe handles different types of training well. For easy days, it offers excellent comfort, and for faster efforts, it doesn’t feel overly bulky. I also wear it for gym workouts, where it provides good comfort and support. Overall, the Megablast is a versatile and enjoyable daily trainer that works well for runners looking for a highly cushioned shoe that can handle more than just easy miles.
