Specifications
Bont GT4 Inline Speed Skate
Built for speed, shaped by experience
GT4 starts with Bont’s 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 Bont’s 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 Bont’s 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 GT4’s 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.
