MAGIC SPEED 4 brings carbon propulsion and lightweight speed to everyday training
What Our Gearhead® Experts Are Saying:
"I laced up the MAGIC SPEED 4 for tempo runs and was instantly hooked. It’s light and responsive without sacrificing stability. The carbon plate gives me a snappy toe-off, and the upper feels secure without squeezing. It’s my go-to for faster training days and even race day."
We train hard to race fast, and the ASICS MAGIC SPEED 4 helps us do both with confidence. Blending race-day responsiveness with the durability of a daily trainer, this shoe bridges the gap between tempo sessions and long-distance efforts. When we need speed without compromise, the MAGIC SPEED 4 gives us the edge.
The carbon-plate-equipped midsole utilizes TURBO and FF BLAST PLUS cushioning to create a ride that’s both explosive and protective. A lightweight engineered mesh upper keeps our feet cool during high-output runs, and an 8mm drop promotes a smooth transition through every stride. For runners chasing faster splits without sacrificing comfort, the MAGIC SPEED 4 is the perfect training weapon.

A kind of magic speed
They are ok, seem more durable than saucony endorphin. They are not as comfortable on the run, though. Maybe with time they will break in, at about 25 mi so far. Don’t feel much of the carbon spring.

Potential blisters
Great shows, but a got blisters on the first 5 runs I had. After running with them 8 times, it’s fine, but yet annoying in the beginning.

Great Shoes for Many Occasions, Need Breaking In
I like the idea behind these shoes, and they cover a lot of bases. You could use them for races, in addition to tempo and speed workouts. My only concern is that both these and the Magic Speed 3 version give me blisters and bleeding on my ankle.

Don't hesitate to add these to your rotation
These shoes feel amazing. Some of the best foam I have run in for speed work or just a normal run in general

Love them
This shoe is absolutely amazing. It is firm yet bouncy. I have been wearing Asics for over 20 years now and these have got to be my favorite one.

Great shoe, feels fast!
2 pairs and 2 PRs later. Great shoe. I originally sized up half size but went down for my second pair to my usual size, which was better despite both being comfortable. Ran 2 half marathon PRs, and have run it for 20 mile training runs but opted for the Sky Speed for marathon race day.

I would buy something else
The material felt cheap and very firm especially at the heels comparing my other Ascis shoes.

Smooth, effortless ride
Great shoe. It makes me feel like I am running more naturally. Thus, I have improved mechanics and am just a tad faster. It has become my go-to training and racing shoe.

Go to shoe
Bought this a few weeks ago and is now my go to shoe. It just feels good m. I have many training shoes in my rotation but this is the one I gravitate to. Stack isn’t high, firm ride.
