Gaerne SG-12 Motocross Boots Review

gearne motocross boots review

The Gaerne SG-12 is the latest flagship motocross boot in the Gaerne range.

If you are shopping for a premium motocross boot, I highly recommend reading this review as these boots are pretty awesome and there’s a lot of value in them.

Gaerne boots are an Italian made motocross boot and if you have owned Italian products before, you will know that the quality is the best in the world.

If you have owned Gaerne boots before then you would have noticed that they last for a very long time.

Gaerne SG-12 Fitting

Gaerne are built to be a wider fitting motocross boot and suit riders with wider feet.

They come in sizes 7 all the way up to 13 and they do not do half sizes.

I am a 9.5 size boot with a more narrow foot. I first bought the 10 and it was too big for me, even with thick socks.

 If you are a half size with a more narrow foot, I would recommend going DOWN size instead of up as they are roomy. example: if you are a 10.5, buy size 10, not 11.

 But if you have a really wide foot, consider taking the 11 and wearing thick socks.

 Rocky Mountain have their exchange guarantee and they will swap them out to a different size for you if they don’t fit properly (just don’t ride in them and they will happily exchange and even pay for postage).

Gaerne SG-12 Weight and Dimensions

The Gaerne SG-12 weigh in at 12lbs.

Their dimensions are 23 x 16 x 6 inches.

Gearne SG-12 Comfort

Gaerne boots are really comfortable but always remember that they are always super stiff out of the box!

This means that you need to ride them in a few times before you really start to feel their true comfort.

But they are super comfortable when they have been broken in. You will notice the difference.

Adjustable Shin Plate

Also, the shin plate is adjustable! This means that the shin plate can be adjusted at a few points around the plate (using 3 screws) to get the right fit for your leg.

If you have a wide leg, the adjustable shin plate will widen out to accommodate, so they are perfect for narrow and wider legs.

I found the adjustable shin plate to be great for my knee braces.

Do They Fit With Knee Braces?

I always hate it when motocross boots don’t fit around my knee braces properly.

The adjustable shin plate adjusted around them perfectly. Great job Gaerne!

 I was wearing mobius knee braces when I tested these boots.

Gaerne SG-12 Motocross Boots Construction.

The base material is made from premium leather with reinforced plastic throughout the entire boot, which adds to its very high durability and protection levels.

There’s a hard plastic gear shifter cover and also a lot of shock absorbing protection around the heel cup and a rock solid calf plate.

The piece in the middle of the calf area is called the razorback and this controls the stiffness and movement of the boot.

The razorback is connected to Gaernes glide plate system. This is basically a hinge system that can ‘glide’ around rather than just pivot at one point.

I really liked this glade plate design as it gave me a more natural range of movement around my ankle, especially when I’m pushing forward in the attack position.

 The glide plate meant that the boot didn’t bulge at the sides when I pushed forward which was great and added to the boots’ comfort in aggressive riding positions.

Internal Linings.

The inner linings of the Gaerne SG-12 motocross boots have plenty of memory foam all throughout the inner boot which make them really comfortable when you put them on.

Also, they absorb the sweat extremely well and I didn’t notice too much smell after riding them had for a few days.

On this inside, Gaerne use their patented rubber material all the way up the inner side of the boot for excellent heat protection and it’s also excellent for gripping the bike.

The toe box is also pretty low profile which I really like and will help your shifting ability ( I don’t like fat toe boxes as they make it harder to shift).

The toe box also has a steel cap which is removable if you prefer not having steel caps on your boots.

 I prefer the steel cap because it protects the sole from tearing from the boot from the constant impact of riding.

I’ve never had a problem with Gaerne buckles. They are tough, simple to operate and are completely replaceable.

Also, what I like about the Gaerne buckles is that they always seem to work when they are full of dirt and mud.

 I’ve found some other motocross boot buckles seize up when they get dirty which can be a real pain in the ass. Not so with Gaerne.

Are They Waterproof?

Yes, they are fully waterproof, just don’t take them in too deep and let them fill up with water.

If they do fill up with water, get yourself a portable motocross boots dryer to dry them out.

Gaerne SG-12 Motocross Boots Soles

 The soles don’t have as much tread as I would like for enduro work so these boots are more suited for motocross use.

The soles are fully replaceable and you can buy fresh soles and have them replaced if you wear them out.

They are very tough though and wear was minimal though.

They are quite stiff and I couldn’t feel my foot pegs, brake or the gear change the first few rides which I didn’t like.

After about a week of using them though, I felt everything and they are super comfortable.


They are now my favorite boots in my dirt bike kit.
