Description

Explosive Elevation: The Adizero HJ

Experience unreal energy return and a strictly locked-in fit engineered for the jump. The ID0304 is defined by its highly technical construction, designed specifically to handle the unique high-velocity lateral forces of a high jump approach and takeoff. The tactical Core Black foundation is electrified by "Zero Metallic" branding and high-definition "Spark" accents, acting as a primary colour story that looks as fast and fierce as it performs on the apron.

Benefits:

Designed for pro-level stadium performance, these spikes incorporate a dual-lock system featuring a traditional lace closure combined with a hook-and-loop top strap for an extraordinary, supportive, high-jump textile upper. Underfoot, featherlight Lightstrike Pro cushioning provides the essential impact defence needed during the harsh plant, while maintaining extreme responsiveness. The specialised spike plate rubber outsole offers confident, rigid grip, ensuring you maintain optimal stability throughout your successful tackle of the bar. Mindfully constructed, the upper contains a minimum of 50% recycled content, actively working to help end plastic waste.

Key Features:

  • Supportive High-Jump Upper: Specialised textile engineered for high-velocity lateral forces and extraordinary support.
  • Dual Lockdown: Lace closure with an integrated hook-and-loop strap ensures a total locked-in feel.
  • Lightstrike Pro Cushioning: Ultra-lightweight foam that delivers unreal energy return and dynamic comfort.
  • Archfit System: Internal architecture designed for professional, stable, and supportive arch contouring.
  • Rigid Spike Plate: Full-foot plate designed for confident grip and explosive takeoff reps.

Product Details:

  • Product Name: ADIDAS Adizero HJ
  • Colourway: Core Black / Zero Metallic / Spark
  • Style Code: ID0304
  • Weight: 277 grams (Size UK 8.5)
  • Midsole Drop: 1 mm (Heel: 19 mm / Forefoot: 18 mm)

Buyer Guidance & Fit Profile:

  • Who This Product Is Best Suited For: Ideal for competitive high jumpers, track and field athletes, and collegiate jumpers demanding uncompromising lateral containment and explosive vertical energy return during the curve approach and plant phase. Seamlessly coordinates with technical competition singlets, athletics speedsuits, and ultra-thin track socks. Not intended for long-distance track running, cross-country courses, or horizontal jumping disciplines requiring alternative spike layouts.

  • Fit & Sizing Determination: Fits True to Size (TTS) in an ultra-snug, competition Performance Fit. Designed to eliminate all internal foot movement under extreme centripetal forces, the Archfit internal system and dual lace/strap closure fit very closely around the midfoot and heel. Athletes with wider feet (EE width) or those who dislike a painted-on competition feel should consider going a half size up (0.5 size larger) to ensure adequate forefoot room on the rigid full-length spike plate.

  • Recommended Conditions & Activities: Optimised for outdoor and indoor track and field competition surfaces, specifically all-weather polyurethane and Tartan high jump aprons in dry to damp conditions. The full-length rigid spike plate, complemented by perimeter heel and forefoot spikes, provides rock-solid grip and torsional rigidity to convert linear speed into maximum vertical lift without energy leakage.
