The full potential of the GTO boot can now be utilized with the introduction of the Marathon Series!

The Marathon Series GTO skate uses the same boot as the Classic Series GTO, but can be completed with one of our new Symetrics Marathon frames and optional Symetrics Hybrid Ceramic bearings.


The Symetrics Marathon frames are available as a 4x100 and a 4x110mm frame option, that both use the 195mm mount of the GTO boot. The frame is fully optimized to fit under the GTO boot, so no adaptors or spacer plates are needed.

Like the Symetrics Hyperframes, the Symetrics Marathon frames are CNC machined out of extruded 7000 aluminium. The frames have intact sidewalls for optimal strength and control. 


Wheelbase 4x100mm frame: 304,5mm
Wheelbase 4x110mm frame: 334,5mm


The 2021 GTO boot has got several upgrades:

  • The padding in the heel pocket is upgraded for improved fit
  • The nubuck skin is reinforced with ballistic nylon to prevent leather stress around eyelets
  • The internal Quattro mounting plates are now made of aluminium instead of steel. This is not only lighter, it also gives an overall better looking finish.
  • The bottom 3 eyelet sets are now wider apart to allow for more pull on the laces
  • Softfoam added to top of cuff area for improved comfort and fit
  • You can now choose whether you want your GTO skate with Airmesh lining or Onsteam lining.

Airmesh lining provides more comfort and cushioning, while Onsteam lining provides increased responsiveness and a direct feeling. 

The GTO is still made with our trusty nubuck 1.3mm leather.  In 2020 we switched from 2mm to 1.3mm nubuck. The thinner material means the skin is just a little bit more flexible, which results in a better fit. While the older GTO model needed some break in time, the GTO 2021 forms to your feet straight out of the box. In short, the nubuck v2 leather provides the same strength and durability but with a better fit. The straps are also single layered to increase fit and comfort.


The Adapt GTO Hyperskate is the brainchild of skate designer Pieter Wijnant. Being obsessed by hand build hypercars for most of his life, Pieter used his passion and knowledge to create the ultimate hyperskate. By using the same technology and mindset the hypercar industry uses, the Adapt GTO is the pinnacle of skate design. Inspired by the prancing horse, the name GTO was given to the ultimate skate. The GTO race series had no limitations and was banned from motorsports for being too dangerous. All GTO cars that were built were left with no other purpose than to raise the bar for every car ever made. The Adapt GTO is a skate with no other purpose than to raise the bar for every skate ever made.


The GTO shell is a Hyperskate diolene shell, finished with extra layers of black twill 3k carbon for improved responsiveness and a dark look. Like all Hyperskate models, the GTO features the Quattromount. The Quattromount is the most versatile mount in the industry as it fits both 165mm and 195mm frames as well as the new Symetrics Quattro S frame. The mount also provides an extremely low centre of gravity, with the wheels as close to your feet as possible.

Marathon Series GTO Complete

  • Stock & Production Time

    All sizes will be produced on order. 

    Due to production material delivery issues during the pandemic and the exponential increase in demand for inline skates, production time has increased. Production time is about 6-8 weeks right now.

  • Lining material

    You can now choose which type of lining material you want in your GTO skate!

    Airmesh lining is a woven material that has small airpockets. The airpockets trap air which provides cushioning. Adapt airmesh lining also has a backing so this provides even more cushioning.
    Airmesh material is therefore comfortable and forgiving.
    We recommend this material for skaters from all skating levels and especially for first time Adapt skaters.

    OnSteam lining is a thin but resistant material that was specifically designed to be used in sport-specific shoes. It gives great responsiveness and a direct feeling. This material will take your skate to the next level. 
    We recommend this material for skaters that are looking for the most responsive option. It is only recommended for advanced skaters and heatmolding is advised to ensure a perfect fit.
