THIS WOMEN'S SHOE IS FOR: Runners who want trusted support and protection in every step, plus a roomy fit to accommodate feet with unique needs. A roomy toe box accommodates orthotics or provides a better fit for voluminous feet. Updated with the innovative GuideRails support technology, this shoe maximizes comfort and support. Predecessor: Addiction 14. This Brooks Addiction GTS 15 is a certified PDAC A5500 Diabetic shoe and has been granted the APMA Seal of Acceptance. SUPER-SOFT CUSHIONING: BioMoGo DNA, our proprietary cushioning, adapts to your stride, weight, and speed. Why? So it can help protect you by reducing impact on your joints. MAXIMUM SUPPORT: Our innovative GuideRails support technology reduces excess joint movement on the run, adding support beyond your feet to the most injury-prone part of a runner’s body: the knees. BREATHABLE UPPER: 3D Fit Print and engineered Air Mesh create the right blend of stretch and structure for supreme comfort. GENEROUS FIT: Sometimes you need a little extra room to move around in. If you need a roomier shoe for flat or high-volume feet or specialized orthotics, your search is over.
