New Balance Sigma Harmony BOA
A new spin on innovation. The S3 dial features our first-ever anodized aluminum dial built to enhance precision with exceptional grip performance and a unique sound cue that together unlock the full spectrum of performance to fine-tune fit even further. Our new heat welding process replaces stitching to increase adaptability, comfort, and pressure distribution while creating a closer connection to the shoe.
Flexible strength for low-power configurations. CS1 lace uses 49 strands of stainless steel wrapped in nylon to withstand abrasion to shed dirt, debris, and water.
