Running Shoes Hyperion Max BROOKS WOMAN 22.5cm These are thick-soled shoes without carbon fiber, and are recommended. My elementary school daughter used these for jogging, drills, and warm-ups during track practice. They are being sold because she has outgrown them. She wore them in rotation with other pairs for about six months. They still have plenty of life left in them. Suitable for: Long distance/Marathon Track and Field Ekiden (relay race) Running Jogging Please read my profile before purchasing.
