Buy the SP5 unless you have a specific reason not to. It is the fixed one-piece guard, it is the one most people get on with, and the Twister bridge between foot and shin means it moves smoothly with your leg. The SP7 detaches at the foot and adds shin padding — buy that one if you want to adjust how the two halves sit, or if you have already found the SP5 slightly short on shin coverage.
In terms of price, the gap is minimal. So consider it a design decision and not a budget one.
Why this matters more than glove choice
A review of leg-kick research across combat sports found that injury surveillance consistently identifies the lower extremity — ankle, knee, shin and foot — as the most frequent and most consequential injury site in striking. You can read the review here.
Rather than skimp on shin guards and then regret it, read our full breakdown below that is designed to help you make the right choice when looking at two of Fairtex's most popular shin guards.

The SP5
Fairtex call the SP5 their premium standard, and it earns the description. It is the shin guard you will see most often in gyms worldwide.
The patented Twister system connects the foot section to the shin section in a way that lets the two rotate independently. When you check a kick or plant to throw one, your ankle moves and the guard moves with it. A rigid connection fights that movement, and over an hour of sparring you feel the difference in your ankle rather than your shin.
The rest is well judged. Full foot cover, soft inner foam, elasticated support at the back of the ankle and the base of the foot, and a long-lasting velcro back-strap with no metal loop — a small detail that matters, because metal loops can easily cause damage to yourself or partner.
It comes in six colours, and Fairtex publish the shin and foot measurements for every size.
The SP7
The SP7 takes the same materials and solves a different problem.
The foot and shin sections are standalone. They attach by velcro, and the foot protector adjusts in four directions through up to 180 degrees. In practice that means you set where the foot section sits relative to your shin, rather than accepting where the manufacturer put it.
That is especially useful for a specific group of people: anyone whose proportions sit awkwardly between sizes, anyone who has found a fixed guard rides up or sits low, and anyone who wants the foot section angled differently for kicking than a fixed guard allows.
The SP7 also carries more padding through the shin than the SP5. If you are the person who ends up checking a lot of kicks that extra coverage is the argument on its own.
The trade-off is that a velcro join is a velcro join. It is secure, but it is one more thing to set correctly before each session, and one more thing that can shift if you set it badly.
Fit and sizing
Both run to four sizes, and both should be judged the same way: the guard should cover from just below the knee to the top of the foot, with no gap at the ankle when you flex it, and it should not rotate around the leg when you twist.
Fairtex publish measurements for both the SP5 and SP7 — shin length and foot length for each size — and those numbers are the most reliable way to order.

Who each one suits
Buy the SP5 if
- You want the guard most gyms are already wearing, for good reason
- You value ankle mobility — the Twister bridge is the whole point
- You are ordering without trying them on and want published measurements
- You want the widest colour choice
Buy the SP7 if
- You want to set where the foot section sits rather than accept a fixed position
- You check a lot of kicks and want more shin coverage
- A fixed guard has ridden up or sat low on you before
- Your leg proportions fall awkwardly between standard sizes
If neither is quite right
Fairtex make a deep shin guard range and these two are not the only options.
The SP8 is described by Fairtex as the culmination of the design work across the SP5 and SP7, with double shin padding — the pick if maximum protection is the key criterion. The SP9 Ultra Ergo is the newest, built around their open system so the guard moves with the leg, and has become very popular very quickly The SP3 is the double-padded option at a lower price, and a sensible first pair.
If you are still assembling your first kit, our Muay Thai equipment guide for beginners covers everything else you will need alongside them.
The verdict
The SP5 is the better default. It is the more elegant piece of design — the Twister bridge solves the ankle-mobility problem properly rather than working around it, and for most people that matters more day to day than the ability to easily adjust does.
The SP7 is the better guard for a smaller group with a specific need: more shin coverage, or a fit that a fixed guard has never quite delivered. If you are in that group you will already know it, because you will have spent many a session pulling a shin guard back into position.
FAQs
Is the Fairtex SP5 or SP7 better?
The SP5 for most people. Its Twister bridge lets the foot and shin sections rotate independently, which preserves ankle mobility through kicks and checks. The SP7 is better if you want to adjust where the foot section sits, or want the extra shin padding it carries over the SP5.
What does detachable mean on the Fairtex SP7?
The foot protector and the shin protector are separate pieces that attach with velcro rather than being permanently joined. The foot section adjusts in four directions through up to 180 degrees, so you set its position relative to your shin instead of accepting a fixed one.
Do Fairtex shin guards run small?
They run true to the published measurements. Fairtex list shin length and foot length for every SP5 size, and those figures are the reliable way to choose. Measure from just below the knee to the top of your foot and match it to the chart rather than guessing from shoe size.
Are Fairtex SP5 shin guards good for beginners?
Yes. They are the most widely used shin guard in the range, they protect well, and the ankle mobility makes them comfortable through long sessions while you are still building conditioning. The SP3 is a lower-priced alternative if budget is the deciding factor.
What is the difference between the SP5, SP7 and SP8?
The SP5 is the fixed one-piece standard. The SP7 detaches at the foot for a customisable fit and adds shin padding. The SP8 combines the design work from both and adds double shin padding, making it the most protective of the three.
