I haven't even tried it on. Thank you. Product Description ■ JSAA Standard General Work (Type A) Certified Protective Sneakers ■ Lightweight type ■ Durable opening: Synthetic leather is used on the opening (inside), which is prone to wear and tear, making it more durable than mesh. ■ Toe reinforcement: The toes, which are easily damaged, are reinforced with durable artificial leather. ■ Reflects light: Reflective material is used to reflect light during nighttime work. ■ Breathable: The tongue (upper part) has a breathable structure that prevents stuffiness. ■ Mesh is used on the sides of the shoes: Adds breathability to the feet, which are constantly moving for long periods of time. ■ Lace storage: The shoelaces can be stored in the tongue (upper part) to prevent them from coming undone and getting caught during work. ■ Hard resin toe cap ■ S type SⅡ sole ※ This is different from JIS standard certified safety shoes. ※ The actual color may differ slightly depending on the environment of your computer.
