The Mizuno Monarcida is the line most players will meet first. It is built to be forgiving rather than specialised, with a synthetic upper, a wide fit on several models, and a price that makes it a realistic first pair.
It is also where Mizuno’s reputation for wide-fitting boots comes from, though that reputation does not hold across their whole range. This guide explains the technology, the tiers, and why the rugby version sits apart from the rest.
What’s inside a Monarcida
The Monarcida takes its design cues from the Morelia, but the materials underneath are chosen for durability and comfort rather than touch. As with the rest of the range, not every boot carries every technology, so treat this as a glossary for reading product pages.
Artificial leather upper
Rather than kangaroo leather, the Monarcida uses a synthetic upper. Mizuno describe a soft artificial leather on the entry versions for durability and flexibility, and a microfiber artificial leather higher up the line for a snugger hold.
A synthetic upper will not adapt to your foot the way leather does, but it needs less specific care and copes well with being wet and muddy — a reasonable trade if the boots see a lot of use and not much maintenance.
ZERO GLIDE insole
An insole designed to grip the underside of the foot and reduce it sliding inside the boot. Mizuno credit it with improving grip and steadiness underfoot, and it appears across the line — some listings call it a grippy insock.
The aim is a more secure feel when accelerating or changing direction, which is useful for players still building confidence in their footing.
The SI screw-in soleplate
SI is Mizuno’s screw-in sole, with metal studs that come out using a stud key. Mizuno do not publish what the letters stand for, so treat it as a name for the soleplate rather than an abbreviation with a known meaning.
The practical benefit is that the studs are replaceable, so they can be swapped as conditions change through the season or renewed as they wear rather than replacing the boots.
Worth keeping straight: SI describes the sole, not the pitch. Listings written as “SI SG” are naming the soleplate first and the ground second. They are two separate pieces of information.
Engineered Fit Last Neo
The shape the boot is built around, aimed at a lightweight, barefoot feel. It appears on upper Monarcida versions and is the same fit thinking Mizuno use further up the range.
The Monarcida tiers
The Monarcida ladder is shorter than most of the range. Mizuno describe Pro as their mid tier and Select as entry level, with the Rugby SI sitting outside that structure as a separate model.
| Model | Upper | Position | Best for |
|---|---|---|---|
| Select | Soft artificial leather | Entry | First pair, wide-fit option |
| Pro | Microfiber artificial leather | Mid | A more refined build |
| Rugby SI | Artificial leather | Outside the ladder | Rugby on soft natural ground |
Some UK retailers use other tier names on Monarcida listings that do not appear in Mizuno’s own range. Where that happens, it is more reliable to match on the soleplate and the surface than on the tier word.
Select — the entry model
Mizuno describe the Select as entry level, and they specify a wide fit on it. A soft artificial leather upper and the ZERO GLIDE insole make it the most forgiving starting point in the line.
It is the lower-cost way into the range, and the version to look at if width is your concern.
Pro — the step up
Mizuno position the Pro as their mid tier. Expect a more refined upper — microfiber artificial leather rather than the softer entry material — for a snugger hold and better durability.
It is the more refined construction without moving to another line.
Rugby SI — outside the ladder
The Rugby SI is the one to know about, and it is not a rung on the Pro-and-Select ladder. It is a separate model, and one of the few boots that sits in Mizuno’s own rugby range rather than being a football boot a retailer has shelved under rugby.
Mizuno describe it as an entry-level rugby boot for players seeking reliable performance across pitch surfaces, with a comfortable wide fit, and it pairs that with the screw-in metal soleplate and replaceable studs.
It is the rugby-specific option in the line, built for soft natural ground.
What Neo means on a Monarcida
This is a genuine trap. On a Morelia, “Neo” is part of the boot’s name. On a Monarcida, Neo is the generation marker — the range runs Monarcida, then Monarcida Neo, then Neo II, then Neo III.
Two things follow. Monarcida does not have a fourth generation, so a boot listed as “Neo 4” belongs to the Morelia line. And a Monarcida Neo III is not the equivalent of a Morelia Neo III — the numbering does not line up across families.
Fit and sizing
Mizuno explicitly describe several Monarcida models as wide fitting, including the Select and the Rugby SI. That is a manufacturer specification rather than a reviewer observation, which makes this the more dependable place to look if width is your main concern.
Do not carry that assumption across the rest of the range. Reviewers generally describe the Morelia as running on the narrow side, and the Alpha is cut close for speed. If a Morelia has felt tight, a wide-fit Monarcida is worth trying.
Our rugby boot size guide covers how to measure properly if you are between sizes.
Which Monarcida should you buy?
- Rugby on soft natural ground: the Rugby SI, for the screw-in metal studs
- A lower-cost entry point: the Select
- A more refined build: the Pro
- You need a wide fit: the Select or the Rugby SI, both specified wide by Mizuno
- A hard-wearing second pair: the synthetic upper needs less specific care
Then choose your surface. Soft-ground versions generally use longer studs designed for softer natural grass, while firm-ground versions use shorter moulded studs for firmer conditions.
Frequently asked questions
Are Monarcida boots wide fitting?
Mizuno explicitly specify a wide fit on several Monarcida models, including the Select and the Rugby SI. That does not automatically apply to every boot in the line, so check the individual product.
Is the Monarcida a rugby boot?
The Monarcida Rugby SI sits in Mizuno’s own rugby range. Other Monarcida versions are football boots. The classification does not carry between versions, so check the specific product.
What does SI stand for?
Mizuno do not publish an expansion. It names the screw-in soleplate with removable metal studs, so treat it as a description of the sole rather than an abbreviation with a known meaning.
Is there a Monarcida Neo IV?
Monarcida generations run Monarcida, Neo, Neo II and Neo III. A boot sold as “Neo 4” belongs to the Morelia line.
Can I replace the studs?
On the SI soleplate, yes — they unscrew with a stud key, so they can be swapped as conditions change or renewed as they wear. Follow Mizuno’s guidance on stud type, and your club or competition’s rules on what is allowed.
Is the Monarcida a good boot for beginners?
Mizuno describe the Rugby SI as an entry-level boot for players seeking reliable performance, and the line is built around a forgiving fit and a durable synthetic upper. That combination tends to suit players starting out.
