How It Fits

• Length: Recommended fit is a 1/4-inch to 3/4-inch space between the end of your toes and the end of the shoe. This shoe fits a half- size small for a correctly measured foot. Go up 1/2 size, compared to most of your dress shoes, for a good fit. For example, if your foot measures an 8 then you should probably order an 8.5.
• Heel: Medium to narrow.
• Mid-foot: Low arch and a medium volume fit.
• Forefoot: True medium with a deep toebox.

Pronation Control Technology

• Midsole: Multi-density TS2 provides support for moderate to severe over-pronation. Extended web technology provides additional pronation control.
• Shape: Semi-straight last further contributes to the support nature of this shoe.
• Construction Last: Absorb strobel last provides comfort in a stability oriented package.

Cushioning Technology

• Midsole: Full-length ACTEVA resists compression, provides extra durability and a responsive ride.
• Heel: Absorb SBS provides excellent shock absorption at heel impact.
• Forefoot: Absorb SBS is placed under the forefoot for excellent response and protection.

Outsole Technology

• N-DURANCE carbon rubber in high-wear areas for added durability. Blown rubber is used strategically to decrease weight and increase cushioning and flexibility.

Upper Materials

• Air Mesh provides great breathability. Synthetic microfiber overlays offer support.
