Technology
8MM

Cushioning is distributed more evenly between the heel and forefoot in shoes with an 8mm offset. The result? Your body stays in a more balanced and comfortable position with every foot strike.
IBR+

iBR+ is a supremely lightweight but durable outsole rubber that enhances your shoe’s other cushioning elements.
TRI-FLEX

Increases force dispersion over a greater surface area while also delivering optimal flexibility and traction.
