MEGABLAST has a tall, energetic platform, so the fit needs to keep your foot centred as the shoe starts to roll forward. Too much movement inside the shoe can change the way the cushioning feels once you pick up the pace.
GAIT analysis can help check whether the MEGABLAST suits your stride, especially if you are moving from a lower-stack daily trainer into something with more rebound. The rocker should feel natural, not like it is pushing you somewhere your foot does not want to go.
Because MEGABLAST is a unisex model in D standard width, the team at Smiths can help check whether the shape works for your foot. That matters if you usually wear women’s standard width, men’s wide width or anything outside a standard running fit.
Bring in your current running shoes if you have them. Comparing the fit and underfoot feel against what you already use will make the decision much clearer.
