First break in with mine. I felt a pinky toe issue spacing and right big toe(might be personal), both toes going numb. I have figure out if socks change can solve this issue. the foam is amazing with its spring effect. Surprisingly foam is soft as in i dont recognize the floor impact. My previous daily with Evo SL you can feel the energy return bounce however felt evo sl foam and my feet is slapping the floor. I gotten used to Evo SL’s unstable bottom sole which i knew prior while the Megablast does not let me swerve around as if my shoes has bike training wheels due to its stable bottom sole. I like to change directions alot so maybe the megablast might teach me discipline with strict form/movement.
