Short verdict: the Mizuno Cyclone Speed 4 is a straightforward indoor volleyball and multi-court shoe built around low weight, a flat stable base and forefoot flexibility. It looks best suited to beginners, school or club players who want a simple court-specific shoe rather than premium cushioning technology. It is not a running shoe, and Zone2 has not court-tested it.
This guide is based on the current Mizuno UK product listing. We have removed the old article’s contradictory international prices, invented customer consensus and retailer-specific delivery promises.
Zone2 verdict
Buy it for: indoor volleyball or general court sessions where a light, flexible and stable shoe is more important than a thick, highly cushioned platform.
Think twice for: frequent high-impact training if you already know you prefer substantial cushioning, outdoor use, road running or anyone who needs a published wide-fit option.
Main trade-off: Mizuno has reduced the amount of outsole rubber to keep the shoe light. That may help it feel less cumbersome, but the manufacturer does not publish a weight or durability test on the UK page. We therefore cannot turn “lightweight” into a measured comparison or promise how long the outsole will last.
Verified Mizuno Cyclone Speed 4 specifications
| Item | Current manufacturer information | What it means |
|---|---|---|
| Primary category | Unisex volleyball shoe | Designed for indoor court movement, not running mileage. |
| Surface | Indoor | Use on clean sports-hall flooring; it is not sold as an outdoor shoe. |
| Stack | 11.5mm | A relatively low court platform; Mizuno does not specify heel and forefoot measurements separately on the page. |
| Midsole | Described by Mizuno as soft and responsive | A manufacturer claim about feel, not an independent lab measurement. |
| Outsole shape | Fully flat with rounded heel | Intended to support stability and smoother heel contact during court movement. |
| Flexibility | Smooth bending grooves in the forefoot | Designed to let the front of the shoe flex during quick changes of direction. |
| Weight | Not published on the UK product page checked | Mizuno calls it lightweight, but there is no number for a fair model-to-model comparison. |
| Width options | No separate wide fit listed | Try before committing if you need extra forefoot volume. |
Grip and stability: what the design tells us
Court shoes need to balance grip with the ability to pivot. Too little traction feels insecure; too much uncontrolled bite can make changes of direction awkward. Mizuno says the Cyclone Speed 4 keeps grip and stability while using less rubber, and the fully flat sole is intended to create a stable base.
Those details support the shoe’s intended use, but they do not justify an independent grip rating. Hall dust, floor finish, outsole wear and movement style all affect traction. Wipe the outsole when needed, follow the venue’s footwear rules and replace a pair that has lost its reliable contact with the floor.
The rounded heel is intended to smooth heel strikes. That may be useful during transitions and general movement, but it should not be read as proof that the shoe changes injury risk or technique.
Cushioning and court feel
Mizuno describes the midsole as soft and responsive, while the listed stack is 11.5mm. Taken together, that suggests a lower, court-connected platform rather than the deep foam stack found in many running shoes. The benefit can be a more direct feel when moving laterally; the compromise may be less material between foot and floor.
Players differ in what they need. Body mass, training volume, jump frequency, previous injuries and personal preference can all change whether a lower court shoe feels adequate. Because Zone2 has not worn this model, we will not claim a break-in period, landing feel or number of comfortable playing hours.
Fit and sizing
The unisex UK listing showed sizes 4 to 15 when checked, although actual stock varied by colour and size. Mizuno did not publish a width measurement or recommend sizing up or down. That means the honest answer is to start with your measured size and try the shoe with your usual court socks.
During a fit check, look for a secure heel, enough toe clearance to avoid contact during stops, and a midfoot hold that does not require painfully tight lacing. Make a few controlled lateral movements on an appropriate indoor surface if the shop or returns policy permits. If your toes press the sidewall or your heel lifts repeatedly, a different last may be better than forcing a size compromise.
Which sports is it for?
Volleyball
This is the clearest match: Mizuno categorises the shoe under volleyball and describes it as an all-round indoor model. The flat base, forefoot grooves and low-weight goal all make sense for general court movement.
Badminton, squash and other indoor courts
Mizuno calls it a multi-court all-rounder, so it can be considered where the venue allows non-marking indoor footwear. Sport-specific preferences still matter. A badminton or squash player who wants a particular outsole feel, torsional structure or fit should compare it with models designed and tested specifically for that movement pattern.
Running and outdoor walking
No. The Cyclone Speed 4 is specified for indoor surfaces and built around court stability and flexibility. Outdoor use can expose an indoor outsole to abrasive, dirty or wet surfaces it was not designed around. For road running, choose a running shoe matched to your gait, comfort and training. For everyday walking, a walking or running-derived shoe is a more direct starting point.
Who should buy it?
- Good match: a beginner or recreational volleyball player wanting a dedicated indoor shoe without premium-model complexity.
- Good match: a school or club player who values a flat stable base and flexible forefoot.
- Possible match: a multi-court athlete who can try the fit and accepts the modest published specification.
- Poor match: a runner, outdoor trainer or buyer looking for a thick max-cushioned platform.
- Poor match: someone who needs a confirmed wide fit or wants a published shoe weight before buying.
Price, stock and value in the UK
Mizuno UK displayed a £60 list price when this guide was checked on 17 July 2026, but the colour reference was out of stock online. Both facts can change. Rather than treating a temporary price as the verdict, compare the Cyclone Speed 4 with available court shoes on fit, surface, returns and total delivered cost.
At that listed price, its proposition is easy to understand: a brand-name, court-specific entry model with a flat outsole and flexible forefoot. Value becomes weaker if poor fit means you cannot move confidently, so availability in the right size matters more than chasing a small discount. Zone2 has no affiliate link or paid placement in this guide.
Frequently asked questions
Is the Mizuno Cyclone Speed 4 good for volleyball?
It is designed and categorised for volleyball, with a flat sole, forefoot flex grooves and a lightweight design goal. Whether it is good for you depends on fit, desired cushioning and playing volume. Zone2 has not court-tested it.
Is the Cyclone Speed 4 a running shoe?
No. Mizuno specifies an indoor surface and markets it as a volleyball shoe. Choose a purpose-built road or trail model for running.
How much does the Cyclone Speed 4 weigh?
Mizuno describes it as particularly lightweight because it uses less rubber, but the UK page checked does not publish a weight. Be cautious of unsourced numbers that do not state the size or whether they refer to one shoe or a pair.
Does it fit true to size?
The official listing does not make that universal claim or provide a width measurement. Start from your measured size, try it with court socks and prioritise heel hold and toe clearance over the label on the box.
Can the Cyclone Speed 4 be used outdoors?
It is specified for indoor surfaces. Outdoor use is outside the published design intent and may affect traction, cleanliness and outsole life.
