In the parallel No. 1 family, the \"Boost\" designation brought a new third layer (elastic resin coating) that fundamentally changed the string's feel. In the No. 7 family, the Boost is more evolutionary — it adds 3D Knit to the original's already strong Deep-Re-Dipping foundation, creating a string where durability is engineered from two independent angles simultaneously: polymer saturation from outside (Deep-Re-Dipping) and fibre interlocking from within (3D Knit).\u003c\/li\u003e\r\n \t\u003cli\u003eUnderstanding why two durability technologies together matter more than one requires understanding how strings typically fail. Most string performance degradation happens through two mechanisms: fibre separation (fibres within the multifilament core progressively pull apart from each other under repeated impact, causing the string to lose stiffness and response) and polymer breakdown (the coating and outer nylon degrade from abrasion, moisture, and UV exposure over time). Deep-Re-Dipping addresses the second mechanism — polymer saturation resists external breakdown. 3D Knit addresses the first — three-dimensional fibre interlocking resists internal fibre separation. The No. 7 Boost attacks both failure modes simultaneously.\u003c\/li\u003e\r\n \t\u003cli\u003eThe practical implication for Indian players is straightforward: the Li-Ning No 7 Boost Badminton String holds its playing characteristics most consistently over time. At week eight or ten of a string's life — when an original No. 7 has experienced some fibre separation and slight feel change — the Boost's 3D Knit construction means the fibres are still more cohesively bonded, maintaining a closer-to-day-one response. For Indian players who restring seasonally or every 2–3 months, this extended consistency is the real-world value of the Boost premium.\u003c\/li\u003e\r\n \t\u003cli\u003eIn all other respects — feel, tension, playing character — the Li-Ning No 7 Boost Badminton String behaves identically to the original No. 7 on day one. Both are soft, forgiving, comfortable 0.70mm strings. The Boost's value is in the back half of its lifespan, not the first session. If your restringing interval is short (every 2–4 weeks), the original No. 7's durability is more than sufficient and the Boost premium is hard to justify. If your interval is long (every 2–6 months), the Boost is the better investment per string set.\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003ch2\u003eString Character Breakdown of Li-Ning No. 7 Boost Badminton String:\u003c\/h2\u003e\r\n\u003cul\u003e\r\n \t\u003cli\u003e\n\u003cstrong\u003eGauge — 0.70mm (Thick\/Durability):\u003c\/strong\u003e Identical to the original No. 7 — maximum durability gauge with more nylon fibre per cross-section for resistance to impact stress, abrasion, and breakage. The 0.70mm gauge is the foundation of the No. 7 family's durability identity.\u003c\/li\u003e\r\n \t\u003cli\u003e\n\u003cstrong\u003eCore — High Polymer Nylon Multifilament:\u003c\/strong\u003e Same high polymer nylon core as the original No. 7 — greater elasticity, strength per fibre, and fatigue resistance than standard nylon. The high polymer designation reflects longer, more densely organised nylon chains at the molecular level.\u003c\/li\u003e\r\n \t\u003cli\u003e\n\u003cstrong\u003e3D Knit Technology — Fibre Interlocking:\u003c\/strong\u003e The defining Boost upgrade. Three-dimensional filament interlocking creates more contact points between fibres across all three spatial planes — not just the two-dimensional wrap points of standard braiding. Distributes impact stress more evenly across the string's cross-section, reduces local stress concentration that causes premature breakage, and maintains more consistent playing feel as the string ages. Works alongside Deep-Re-Dipping to address the two primary failure modes of string degradation simultaneously.\u003c\/li\u003e\r\n \t\u003cli\u003e\n\u003cstrong\u003eDeep-Re-Dipping Technology — Polymer Saturation:\u003c\/strong\u003e The same Deep-Re-Dipping process as the original No. 7 — repeated polymer immersion fills micro-gaps between fibres, prevents external moisture absorption, and dramatically extends string life. In the Li-Ning No 7 Boost Badminton String, Deep-Re-Dipping and 3D Knit operate on different aspects of the string structure, making the two technologies genuinely complementary rather than redundant.\u003c\/li\u003e\r\n \t\u003cli\u003e\n\u003cstrong\u003eOuter — Heat Resistant High-Intensity Nylon:\u003c\/strong\u003e Same outer specification as original No. 7 — structural integrity and even tension distribution. Heat resistance ensures consistent feel in warm playing conditions.\u003c\/li\u003e\r\n \t\u003cli\u003e\n\u003cstrong\u003eCompound Nylon Coating — Soft Feel Preservation:\u003c\/strong\u003e Same compound nylon hit-absorbing coating as the original No. 7 — the source of the soft, comfortable feel. In the Boost, the 3D Knit construction's more cohesive fibre structure helps preserve this coating's integrity for longer into the string's lifespan, meaning the soft feel is maintained more consistently over extended use.\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003ch2\u003ePerformance Ratings — Li-Ning No 7 Boost Badminton String:\u003c\/h2\u003e\r\n\u003ctable\u003e\r\n\u003ctbody\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\r\n\u003ctd\u003e\u003cstrong\u003eScore\u003c\/strong\u003e\u003c\/td\u003e\r\n\u003ctd\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003e\u003cstrong\u003eRepulsion\u003c\/strong\u003e\u003c\/td\u003e\r\n\u003ctd\u003e\u003cstrong\u003e6 \/ 10\u003c\/strong\u003e\u003c\/td\u003e\r\n\u003ctd\u003eIdentical to the original No. 7 — 0.70mm gauge produces moderate repulsion appropriate for the durability string tier.
