The v7 of the "4040," named after the 40 home runs and 40 stolen bases, is now available with rubber cleats for kids and junior players. Using a baseball last designed for kids and juniors, the upper is made of durable synthetic leather. A thick midsole protects the feet from hard ground. The outsole features rubber studs optimized for kids and junior players, delivering performance on all surfaces, from hard ground to artificial turf. The above is an excerpt from the official website. I purchased these for a family member for baseball, but they broke their bone around the same time and outgrew them. They have been stored at home. The size is 22.0 cm. Thank you for your consideration.
