Review on Enhanced Performance with New Balance 3000V5 Molded Baseball Men's Shoes in Athletic Design by Carl Watkins

My son is 10 and plays in the minor league. Field time is about 2.5 hours, 3 times a week. In the 3rd week of use it started to slip while playing. His boots were inspected and to my surprise the boots had come down to the tips of his toes. His old pair of boots were worn for 3 months before wearing down to the same point. Same make, size and model. The only difference was the color. What could have caused this defect?
