Product Description

Built for speed, shaped by experience

GT4 starts with Bonts last, refined over decades by founder and designer Mr. Inze Bont. That foundation creates the close, performance fit skaters expect from an inline speed skate, so your foot sits low and locked in, ready to push through corners and accelerate cleanly. Bont builds the shell using one-piece manufacturing, a technique usually reserved for higher-priced custom boots, to create a stiff, consistent platform that does not rely on multiple glued sections. The result is a boot that feels planted, transmits energy efficiently, and stays true to its shape season after season.

Carbon composite base with custom comfort

Under the microfiber skin is a carbon composite base laminated with Bonts epoxy thermoset resin. This resin system allows targeted heat molding so you can fine-tune hot spots and pressure points for a glove-like feel. If you have ever struggled with numb toes or ankle rub, the GT4 gives you that extra adjustability to dial it in. For oven and spot molding guidance, follow Bonts heat molding instructions for composite boots.

A quick note on molding terminology. GT4 does not include additional thermoplastic sheets inside the boot, a feature found on some Bont models to expand the molding range. Many skaters do not require that level of reshaping, and the GT4s resin-based heat molding provides ample fine-tuning for most feet. This keeps weight low and value high while preserving the secure feel that speed skaters prefer.

Fit that lasts

Stretch can quietly ruin a boots performance over time. Bont weaves an anti-stretch material into the boots structure, stitch-locking it between the skin and liner. This reinforcement helps the upper resist creep so the fit you love on day one stays consistent through hundreds of training hours. Fewer mid-season surprises, more predictable edge control.

Practical performance for real-world training

GT4 is built to be skated hard. The carbon composite construction strikes a balance between stiffness for strong pushes and a touch of forgiveness for imperfect roads. The 12 mm pitch suits modern racing technique, promoting stable knee tracking and efficient under-body weight transfer. Vents at the tongue help manage heat on summer sessions, and the micro-adjust buckle and laces let you set and forget before you roll out.

Mounting and compatibility

The boot uses standard 2-point mounting across common spacings, so it integrates easily with Bonts 2PF racing frames as well as many third-party options. That means you can start with your current frame and wheels, then upgrade components over time without changing your boot fit. For riders building a full package, Bonts 6061 frames are a reliable match with proven durability for training and race days alike.

Frequently Asked Questions

Is the GT4 boot heat moldable?
Yes. The carbon composite base uses Bonts epoxy thermoset resin, which allows heat molding for fit refinement. Follow Bonts heat molding guide for composite boots to adjust specific areas safely.

How does GT4 differ from the Jet boot?
GT4 does not include additional thermoplastic sheets inside the boot, which some riders use for more extensive reshaping in an oven. Many skaters do not need that extra range, and GT4s resin-based molding covers typical hot spot adjustments while keeping the package lighter and cost-effective.

What frames and wheels work with the GT4?
Most 2 point racing frame within standard mount spacings, 195 mm, will fit. Pair it with Bonts 2PF 6061 frames and Elemental training wheels for a reliable all-around setup, or mount your preferred racing frame and speed skate wheels based on surface and distance.
