This is a review of the Leatt GPX 5.5 FlexLock Boot.


Rule #1

Buy the best dirtbike or motocross gear you can afford.

While Leatt Racing gear has not been making boots for as long as some of the other brands like Alpinestars or Gaerne, they have been making safety gear for dirtbiking for a very long time.

The Leatt GPX 5.5 Flexlock boot really reminds me a hybrid between the Alpinestar boots and the SIDI Boots.

This is Leatt’s top-of-the-line boot that compares to the following dirtbike boots:

The Leatt GPX 5.5 FlexLock Boot is a high-quality, comfortable riding boot that keeps you secure and safe on your motorcycle. The FlexLock system secures the foot in an anatomical position for increased comfort, while the material won’t stretch and cause blisters over time like other brands do. With four sizes available and an intelligent design that flexes with your foot as you ride, these boots will keep you comfortable all day long without sacrificing safety.

Durable all-day comfort

The Leatt GPX 5.5 FlexLock Boot is not just a good-looking boot, it’s comfortable too. The soft, cushioned insole and leather upper keep your feet feeling fresh all day long. The FlexLock system allows the boot to flex with your foot while the ankle cinch strap provides a secure fit. Plus, they are extremely light weight and easy to walk in!

Locking mechanism for a secure fit

You’re going to want your feet to be held in place. The 5.5 FlexLock system keeps your foot secure on the dirtbike, and helps prevent injury.

Leatt Boot flexes in the natural positions you need it to

Leatt’s GPX 5.5 FlexLock boot flexes in the natural positions you need it to, and it is comfortable all day long. I spend a lot of time on my knees and the higher-ankle design allows me to bend over without restriction or discomfort. The dual-compartment calf design is great for keeping your foot warm while riding and cold when off the bike.

They provide great support for your ankle without restricting movement, so you can enjoy every ride without worrying about slipping off your pedal or feeling tightness in your calves. Plus, these boots have many features that make them easy to use and care for: they come with an adjustable cuff that fits around most sizes of legs; they’re super lightweight at just over 1 pound apiece; they have velcro straps instead of laces so there’s no fussing around trying find just right fit when putting them on before riding off into sunset (or whatever time it might be). The only drawback we found is price – these cost more than twice what some competitors do which makes them hard justify unless money isn’t an issue!

DirtBike Sam’s Opinion:

Right now with this being on sale……You are getting a top-of-the-line dirtbike boot without having to pay $600 dollars.

Its a great buy and will be as good as the other top-of-the-line motocross boots. If you are into enduro and you are considering dirt bike boots, then I strongly suggest to read this Leatt Flexlock Enduro Boots review.

I also always recommend trying on boots before deciding which one is better. Just about all dirt bike boots have some sort of breaking period so keep that in mind
