361° Big3 Quick 4.5 Basketball Shoes - Lightweight Guard Specialist

The 361° BIG3 Quick 4.5 was built for one type of player: the guard who makes defenders look slow. At 370g (EU42), it sits firmly in the lightweight performance tier — light enough to feel fast, structured enough to feel safe, and tuned precisely for the footwork-heavy, direction-changing, full-court game of guards and wings.
This isn't a cushion-first shoe. It's a court-feel, responsiveness, and lateral control shoe. If you play with speed, this is your shoe.

Key Technologies
E-REN (E韧) Midsole — Light Foam, Real Bounce The E-REN (Energy Resilience) lightweight foam midsole strikes the right balance for performance players: cushioned enough to protect through a full game, responsive enough to keep your footwork quick and your transitions sharp. No energy lag. No mushy landings. Just clean, direct court feel that lets you feel every movement beneath your feet.
CQT Carbon-Critical Foam Insole A CQT (Carbon-critical Technology) supercritical foam insole sits on top of the E-REN midsole, adding an additional layer of soft, springy comfort underfoot. The result is a layered cushioning system — firm support from the midsole, plush responsiveness from the insole — that delivers a premium in-shoe feel at an accessible price point.
Full-Length Lateral TPU Wrap — Anti-Rollover Protection A continuous TPU frame runs along the full lateral side of the shoe, from heel to forefoot. This wrap-around structure prevents the lateral compression that causes ankle rolls during hard cuts, sudden stops, and physical contact — giving you the confidence to commit fully to every drive without holding back.
ARCHLOCK Midfoot Torsion Shank The ARCHLOCK anti-torsion plate at the midfoot prevents excessive twisting of the shoe during lateral loading, adding torsional rigidity that translates directly into stable, controlled direction changes. Less energy lost to flex. More power into the cut.
ETPU Yarn + Jacquard Knit Upper The upper combines ETPU (expanded TPU) yarn with a jacquard knit construction — a technique that varies weave density across different zones to deliver support where you need it and breathability where you want it. The result is a lightweight, breathable, snug-wrapping upper that keeps your foot locked in without feeling restrictive or hot.
Heat-Fused Overlays + Side TPU Frame Critical zones of the upper are reinforced with heat-fused bonded overlays and side TPU structural frames, adding lateral support and containment without adding unnecessary weight.
Dense Triangle-Pattern Rubber Outsole The full-coverage rubber outsole features a dense, multi-directional triangle traction pattern that bites into the floor on every cut, stop, and pivot. Sharp stop response, stable lateral grip, and durable enough for both indoor hardwood and outdoor concrete courts.
