ON THE RUN
Sidney: It was one of those weeks: clumsy falls, face-palm mistakes, and questionable decisions. First, I ate it on my mountain bike, bruised and scraped. The next morning, I woke up to find dried blood on my ankle from a ripped blister I hadn’t even noticed, courtesy of my first run in the Sonicblast. Add on top of all of that, a calf twinge that just kept nagging at me. With bruises on one side and a mystery blister on the other, I laced back up anyway.
On the run, the Sonicblast instantly reminded me of the Saucony Endorphin Speed. In fact, I couldn’t stop comparing the two the entire time. To really understand where this fits, I even swapped shoes mid-run, going from the Sonicblast to the Superblast 2. Back-to-back miles showed how each “Blast” family member has its own personality. The Superblast 2 felt softer, calmer, and stable, while the Sonicblast was twitchy and alive, like a cheetah about to pounce. This shoe doesn’t want to chill, it wants to go.
THE FIT
Sidney: First things first: the fit gave me problems. On my first run, I had extreme foot numbness, full-on tingling until I had to stop to wiggle my toes. It wasn’t from tight lacing but from the lack of arch support. Adding an insert fixed it, but it’s something to note if you need a little extra support in that area. Just looking at the shoe you can see how much the midfoot narrows and tapers in the center of the arch, which added to that unstable feeling. The toebox is fine, not overly roomy but not cramped either. The upper is nothing to write home about, but nothing to complain about either. It keeps you locked down, strapping you in for the ride without choking you out and I didn’t notice any rubbing or pinch points.
THE FEEL
Sidney: The Sonicblast doesn’t want to chill at party pace. I’ve heard people say if you run 10+ minute miles this shoe isn’t for you, and while that comment gives me the ick, I get it with this shoe. I’m not a speed demon, and at a 10–11 minute warm-up pace the Sonicblast felt awkward. But the moment I picked it up, I could relax, settle in, and feel the comfort of the shoe propelling me forward. At faster paces and strides, this shoe really shines.
Visually, the Sonicblast feels like it’s all forefoot. But the numbers tell a different story: 46mm in the heel and 38mm in the forefoot, for an 8mm drop. Even with that much cushion under the heel, it still comes across feeling minimal in the back, while the forefoot feels like the star of the show. Think of it as the opposite of a mullet: business in the back, party up front.
By comparison, the Superblast feels chunky throughout, a big, built-up heel paired with an equally stacked forefoot, giving it a bulkier and more cushioned overall feel. Next to the Superblast, the Sonicblast looks stripped down, more streamlined, and ready to pounce.
All together, it feels like if the Novablast and Endorphin Speed had a baby, Sonic got the plate from mom and the bounce from dad.
THE NITTY GRITTY
Sidney: I see the Sonicblast as a long-run workout shoe, not necessarily your everyday mileage grinder. It feels like it’s built for speed sessions and focused workouts. If I’m going out for an easy long run where I want to feel some oomph, I’ll grab the Superblast 2. If I’m going out for a long run speed workout I’ll grab the Megablast for more support and comfort. But for workouts or days I want to pick up the pace, the Sonicblast feels alive.
Compared to its family:
-
Superblast 2: cushioned, stable, high-mileage workhorse.
-
Novablast: bouncy daily trainer.
- Megablast: slimmed-down beast, light and fun, race-day wannabe.
- Sonicblast: the serious one — plate, bounce, and a little instability designed to keep you on your toes.
One big compliment to the Blast family is how minimal they all feel. The uppers are consistently light, and even with their sometimes chunky midsoles, the bounce stays lively while the overall weight feels effortlessly weightless. The Sonicblast carries this same Blast DNA, checking all the boxes, and comes in at 256g for men and 223g for women. On foot, that weight feels almost invisible, keeping you quick on your toes.
THE RUNDOWN
Sidney: The Sonicblast isn’t for everyone, and honestly, it’s not for me. But I can see who will love it: runners who want a plated shoe that doesn’t feel as casual as the Endorphin Speed, but still isn’t as aggressive as a full-blown racer. It’s twitchy, fast, and alive, a bridge between your plated daily trainer and your plated racing shoe. That minimal, weightless feel does come at the cost of some stability, but for the right runner it’s worth it. Best saved for speed workouts, strides, or long-run workouts where you want a plated kick, the Sonicblast is the sharpest tool in the Blast lineup yet. Saucony might want to keep an eye out, because Sonic is coming.
