Purchased around December 2025. I tried them on at home, but the size didn't fit, so I'm selling them. I haven't used them outside, so there's almost no dirt. Thank you. Quantum Leap - An otherworldly bounce, electrostatic type Specifications JSAA certified A-type artificial leather professional sneakers / Heel shock absorption / Slip-resistant / Electrostatic Specifications ● Construction: C-type ● Toe cap: Wide resin ● Upper: Artificial leather / Mesh ● Insole: EVA cup insole (antibacterial and deodorizing) ● Outsole: EVA (QL foam) / Synthetic rubber ● Weight: 800g / foot Features ■ Otherworldly bounce QL foam We have developed a new midsole "QL foam" that makes it easier to take the next step due to the high rebound when stepping on the ground. It's a soft material that you can feel just by pressing it with your finger, and it exhibits higher rebound than a normal EVA sole. ■ Electrostatic charge prevention specifications Electrostatic shoes release static electricity from the sole, preventing sparks. ■ Excellent slip resistance High-grip sole that is slip-resistant even on floors with water or oil. Level 5, the highest level in the slip resistance classification, which indicates the degree of slip resistance on a 5-point scale. ■ TPU toe cap Protects the easily scratched toe leather with a TPU toe cap with excellent abrasion resistance. ■ Reflector Reflectors are placed on the upper sides. Reflects car lights at night or in places with poor visibility, improving safety. ■ Wider resin toe cap A wide-design resin toe cap made possible by firmly holding the last and insole. It is about 3mm wider than the conventional wide resin toe cap.
