A Bond That's Better for the Planet

KEEN.FUSION technology fuses the upper to the sole without toxic glues for a longer-lasting bond.

No Glue

KEEN.FUSION uses heat and pressure, not toxic glues, to create a mechanical bond between the upper and the sole.

More Durable

Glue can deteriorate over time. KEEN.FUSION creates a bond that lasts longer.

Less Energy Used

Data from our owned factories suggest that KEEN.FUSION construction requires 3.5 times less electricity use per pair.
