The 361° Biospeed BB 2 “Ice Blade” is built around a performance-oriented basketball shoe structure that combines a lightweight upper, full-length cushioning, a structural plate, TPU reinforcement, and a segmented outsole.
Its design distributes different structural roles across separate layers, with the upper handling containment while the midsole, plate, and support components form the primary underfoot platform.
Lightweight Woven Upper
The upper uses a lightweight woven construction with open textile zones through the forefoot and midfoot. Reinforced synthetic overlays surround the eyestay and extend along the perimeter of the shoe, adding structure to key sections of the upper.
The lacing system is integrated into these reinforced areas, connecting the closure system with the surrounding upper rather than relying solely on the textile layer.
From the top view, the forefoot shows a more open textile pattern through the central area, while denser materials are positioned around the outer edge. This creates a clearly zoned upper construction.
Full-Length CQT QUI!K Cushioning
The primary cushioning layer is a full-length CQT QUI!K midsole.
Instead of using isolated cushioning units at the heel or forefoot, the foam extends through the full length of the platform, creating a continuous cushioning base beneath the foot.
The midsole geometry also features raised sections around parts of the forefoot and rearfoot. These areas visually wrap around portions of the upper and define the outer edges of the cushioning platform.
QUIKBONE Structural Plate
Below the cushioning layer is the QUIKBONE plate, identified in the supplied structure breakdown as a basalt-fiber dynamic carbon plate.
Its geometry extends through much of the platform and incorporates multiple cutouts through the forefoot, reducing the amount of continuous material while retaining a connected structural framework.
The plate forms a structural layer beneath the cushioning system and is designed to support propulsive movement through the platform.
Large-Area TPU Support
A separate large-area TPU support piece is positioned beneath the main plate and cushioning system.
Rather than forming a flat sheet, the component follows the curved geometry of the shoe and extends through a substantial portion of the platform. It adds reinforcement to the underfoot structure and contributes additional support and stability.
Together with the QUIKBONE plate, it creates a layered support system beneath the cushioning foam.
RPU Outsole
The bottom layer uses an RPU outsole with a directional traction pattern.
The tread is divided into different zones across the forefoot and heel, while an opening through the central-rear section exposes part of the underlying structure. This gives the outsole a more segmented configuration than a conventional full-coverage rubber sheet.
The pattern is designed to provide traction while following the geometry of the midsole and support structure above it.
Overall Construction
The principal structural elements of the Biospeed BB 2 include:
- Lightweight woven upper
- Full-length CQT QUI!K cushioning
- QUIKBONE structural plate
- Large-area TPU support piece
- RPU outsole
These components create a layered basketball platform in which cushioning, structural reinforcement, support, and traction are handled by separate but interconnected parts.
Conclusion
The Biospeed BB 2 combines a relatively lightweight upper with a more complex underfoot construction.
Its full-length cushioning forms the primary foam platform, while the QUIKBONE plate and TPU support piece add separate structural layers underneath. The RPU outsole then forms the ground-contact layer beneath the system.
Overall, the design follows a clear layered approach, concentrating much of the shoe’s structural reinforcement within the midsole and underfoot platform rather than relying on a heavily built upper.
