Your boots are the only connection between you and the ground, so you’ll want to ensure you have the right match.
If you've landed here on your search for a new pair of football boots, chances are you're wondering what the differences between all the abbreviations AG/SG/FG/TF/MG are (yes, there are a few), but they can easily be explained.
We all know football boots come in an array of colours and styles, but the real game-changer lies beneath your feet: the studs and soles. Choosing the wrong type of football boot for the surface you're playing on could make the game harder than it needs to be: think slipping mid-sprint, getting stuck in turf, aching joints or worse, a rolled ankle.
Whether you're playing 5-a-side games on synthetic turf, playing league on muddy grass, or hitting the futsal courts indoors, the pitch surface matters when choosing your boot.
In this guide, we'll break down the different football boot surfaces: firm ground (FG), artificial grass (AG), soft ground (SG), indoor (IN), and turf (TF). By the end, you'll know exactly which pair to choose for every game.
Why Football Boot Surfaces Matter
Football is all about quick movements: sharp turns, explosive sprints, sudden stops. Your boots are the only connection between you and the ground, so you'll want to ensure you have the right match.
Wearing the wrong boots could lead to:
- Slipping and sliding (FG boots on a soggy pitch? You could be slipping and sliding).
- Foot and joint pain (using FG boots on artificial grass can put excess pressure on your knees and ankles).
- Shorter boot lifespan (indoor shoes on outdoor concrete won't last long).
Think of it like tyres on a car. You wouldn't race Formula 1 on off-road tyres, right? Football boots are the same. Pick the wrong surface and you compromise grip, performance, and safety.
Types of Football Boot Surfaces
1. Firm Ground (FG) Boots
If you had to pick one pair of boots for the majority of outdoor football, FG boots are your safest bet.
Best for: Everyday players who mostly play on outdoor grass in dry to slightly damp conditions.
Stud pattern: Usually 10–14 studs, either conical (round) for easy rotation, bladed for sharper grip, or hybrids combining both.
Why they work: FG studs penetrate the grass just enough to give stability and traction without sticking too deep.
Avoid on: Muddy or waterlogged fields (you'll slide everywhere) and strongly recommended not to wear on artificial ground with sand and rubber infill as they are not compatible with the additional friction. You will damage the boot, plus this harder soleplate and longer studs can also cause injury and discomfort to the player.

2. Artificial Grass (AG) Boots
Modern football has moved indoors and onto 3G/4G synthetic pitches, and that's where AG boots shine.
Best for: Players who train and play mostly on long-pile artificial pitches (such as 3G/4G astro turf).
Stud pattern: More studs (up to 25) and slightly shorter than FG studs, often hollow to provide optimal grip and reduce pressure on joints and muscles.
Why they work: They spread your weight evenly, reducing the risk of stud lock (when your boot gets stuck in the turf and your knee twists).
Avoid on: Soft or muddy natural pitches as the short studs won't grip.
Some AG boots can also be used on Firm Grounds (FG), although how well they will perform depends on how solid/dry the grass is. There are some hybrid models available. If you're unsure be sure to check with a rebel staff member before buying.
SHOP3. Soft Ground (SG) Boots
When the heavens open and pitches turn into mud baths, SG boots are preferred.
Best for: Wet, muddy, natural grass pitches.
Stud pattern: 6–8 metal screw-in studs, longer than FG studs.
Why they work: They cut through soft ground and give traction where plastic studs would slip.
Avoid on: Firm or artificial surfaces. You'll feel like you're running on stilts, and you could damage the pitch (and your feet).
SHOP4. Multi-Ground (MG) Boots
When you don't want to carry two or three pairs of boots around, MG boots are your all-rounder solution.
Best for: Players who regularly switch between natural grass and synthetic pitches.
Stud pattern: A mix of shorter, strategically placed studs (often more numerous than FG but not as hollow as AG).
Why they work: They spread pressure evenly, offering good traction on different surfaces without over-committing to one type.
Avoid on: Very wet/muddy pitches (SG is better) or indoor courts (IN/TF are made for those).
SHOP
5. Indoor (IN) Football Shoes
Indoor football (or futsal) is a completely different ball game and demands a completely different shoe.
Best for: Indoor courts (wood, polished concrete, futsal-specific surfaces).
Sole type: Flat, non-marking rubber sole.
Why they work: They grip the court for quick pivots and allow maximum ball control.
Avoid on: Any kind of grass or turf as they won't provide enough grip.
SHOP
6. Turf (TF) Shoes
Turf boots are the unsung heroes of football footwear.
Best for: Casual kickabouts, 5-a-side on astro, or training sessions. Older-style artificial turf (short, sand-based) or very hard ground.
Stud pattern: Dozens of small rubber nubs across the sole.
Why they work: They give solid grip on flat, compact surfaces without digging in.
Avoid on: Soft ground or modern long-pile turf as not enough grip.
SHOPYour Quick Cheat Sheet
- FG = your go-to for most natural grass.
- AG = best for synthetic turf.
- SG = muddy pitches, Winter football.
- MG = for switching between natural grass and synthetic pitches.
- IN = futsal and indoor courts.
- TF = hard ground and old-school astro.
FAQs
- Can you wear firm ground boots on artificial grass?
It's strongly recommended not to. FG boots can wear down quickly on AG pitches and may cause stud pressure or knee injuries. If you regularly play on artificial turf, invest in AG boots. - Are AG boots worth it if I mostly play on 3G?
Absolutely. They're designed for the job, offering better grip, reduced injury risk and are likely to have longer lifespan than FG boots. - What's the difference between turf shoes and indoor shoes?
Turf shoes (TF) have small rubber studs for grip on older astro pitches, while indoor shoes (IN) have flat soles for futsal courts. Wearing the wrong one could mean slipping everywhere. - Can you use soft ground boots on firm ground?
Nope. Metal studs are too long for hard ground. You'll feel unstable, risk injury and might even damage the field. - Do I really need more than one pair of boots?
If you only ever play on one surface, one pair will do. But if you switch between grass, turf, and indoor courts, having at least two pairs is the smart play.
Football boot shopping doesn't have to be confusing. Once you know the difference, it's easy to pick the right pair.
