New Balance SD100v2 – MSD100B3

The SD100v2 is New Balance’s short-distance sprint spike — built lighter, lower, and more aggressively than all-around track spikes for athletes who live in the blocks. Inspired by the Vazee Sigma, it wraps the foot in a snug bootie upper and drives every ounce of force through the Pebax plate into the track.

• Full-Length Pebax Spike Plate with 6-Spike Configuration — Lightweight, rigid Pebax plate runs the full length of the forefoot with a 6-pin configuration that delivers maximum traction and explosive power transfer at push-off — optimized specifically for the short-distance sprint mechanics of 100m and 200m events where every millisecond of ground contact time matters
• Ankle-High Bootie Construction — Sock-like bootie upper wraps the ankle and foot in a seamless, snug fit that eliminates interior movement during aggressive block starts and high-frequency stride cycles, providing the locked-in feel sprint athletes need without the bulk of a traditional collar design
• No-Sew Synthetic Upper — Streamlined no-sew construction reduces friction points and interior texture that can cause irritation during intense sprint efforts, while the form-fitting synthetic material conforms closely to the foot for a clean, distraction-free fit from the first stride
• Internal Shank for Structural Support — Built-in internal shank provides targeted midfoot rigidity that supports the sprint position and force transfer without adding perceptible weight to the spike — keeping the shoe structurally stable through the full acceleration phase of the race
• Molded Midsole for Lightweight Cushioning — Sleek molded midsole contributes minimal weight while providing the structural foundation needed to support the Pebax plate and maintain spike geometry under the explosive forces of sprint block starts and full-speed acceleration
• Includes 1/4″ Pyramid Spikes and Wrench — Arrives competition-ready with 1/4″ pyramid spikes pre-installed and a spike wrench included for straightforward replacement across different track surfaces; sized in men’s with women’s equivalent sizing available by adding 1.5 sizes
