Asics MAGIC Speed 4 Athletic Shoes

Description

Upper: High-containment MotionWrap™ mesh supported by an internal midfoot saddle and a structured heel counter to keep the calcaneus held firmly over the center of the shoe.
Midsole Cushioning: Thick dual-density FF BLAST™ TURBO and PLUS stack engineered to absorb vertical landing forces, preventing harsh shock loads from reaching knees and lower back.
Cushioning & Stability Technologies: Full-length plate creates a rigid forefoot platform, minimizing metatarsophalangeal joint bending and relieving stress along the plantar fascia and Achilles tendon.
Outsole: Broad base geometry with full-contact ASICSGRIP™ rubber coverage to maximize ground contact area and eliminate uneven pressure points.

Key Features & Benefits

Forefoot Flex Protection: Rigid carbon-infused plate reduces painful toe-joint flexion during propulsion phases.
Plantar Pressure Relief: Wide midfoot platform and structured plate geometry prevent excessive arch collapse under fast loads.
High-Grade Impact Mitigation: Dual-foam stack absorbs heavy heel and forefoot impacts to protect joint cartilage.
Removable Footbed: Factory liner removes easily to allow compatibility with custom orthotics or sport insoles.

Sizing & Fit Advice

Fits True to Size (TTS). If planning to insert custom rigid orthotics, select half a size up to maintain adequate forefoot depth.

How to Find Your Size (Step-by-Step Guide)

1. Setup: Place a plain sheet of paper on a hard floor, flushed against a flat wall. 2. Position: Stand on the paper with your heel resting gently against the wall (wearing your preferred running/athletic socks). 3. Mark: Mark the furthest point of your longest toe on the paper with a pencil. 4. Measure: Measure the distance from the edge of the paper (wall) to your mark in Centimeters (CM).
Recommended Fitting Margin:
Casual / Everyday Sneakers: Add +0.5 cm to your measured foot length.
Performance Running: Add +0.5 cm to +1.0 cm for comfortable movement and natural toe expansion.

Asics Signature Fit & Characteristics

Performance Fit Profile: Asics running shoes are engineered for a snug, locked-in feel around the midfoot and heel to ensure maximum stability, with optimal room in the forefoot.
GEL™ Cushioning & Arch Support: Due to structured arch support and GEL™ inserts, performance models may feel slightly snugger out of the box compared to casual sneakers.
