ULTIMATE COMFORT AND FORCE REDUCTION PROTECTION.

The Leatt 5.5 FlexLock boot was a 3-year project with long-term development and testing using our Pro athletes from all over the world!

The 5.5 boot is a real head-turner when it comes to looks and style, but the design brief was comfort and protection also, and we nailed it first time.

Leatt's adjustable FlexLock system reduces forces to the ankle by up to 37% and the knee by up to 35% by Locking out the ankle movement when over-flexed, giving you that feeling of security.

Features:

  • Fit: Outstanding comfort with first-class fit, even for wide feet.
  • Closure:
    • SlideLock system: Auto-locking one-way sliding closure for a great seal at the top of the boot.
    • Forged aluminum buckles with Over-lock system and stainless steel base.
  • FlexLock System:
    • Adjustable lower boot flex for personal preference.
    • LockOut of the sideward ankle movement to reduce forces.
  • Force Reduction:
    • LockOut ankle movement provides:
      • Up to 37% reduction of ankle forces.
      • Up to 35% reduction of forces to the knee.
    • Reductions compared to the market leader/most high-end boots.
  • Bike Grip: Flat and grippy inside of the boot for great bike feel.
  • Toe-Box: Low-profile design for easy gear shifting.
  • Ankles:
    • 3D-shaped impact foam over ankles for added protection.
    • Heel grip ankle design for stability when riding on your toes.
  • Sole:
    • DualZone hardness
    • Extended foot peg riding zone for arch and on-the-toes riding style.
    • Steel shank reinforced and CE- certified.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.

Great socks
Size: Medium, Color: Pink - 647
Well-made and comfortable to wear. Great for golf and other outdoor activities. Like them because they do not show above shoes.

These ACTUALLY stay put all day long - I was skeptical, but am so glad I took a chance on these
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I was so skeptical about whether these would stay on my feet all day without sliding down into my shoe - I’ve tried so many socks in the past with the silicone strip on the heel which failed. I’ve owned these for a couple months now and they have never slipped down - they stay put all day! I love the variety of colors to choose from, and the value per pack is great since six pairs come per pack (I thought it was only three when I first purchased and was pleasantly surprised by the additional pairs). They also have perfect thickness - not too warm to wear during the summer months with sneakers; I live in a tropical climate, though, so I’m not sure how they will do in cooler climates. I’ve washed each pair once or twice and the color and quality of the silicone has stayed so far (knock on wood). Overall: high recommend based on my experience so far!
