These running shoes are very light weight. I bought these sneaks for my 11-year old daughter who is always on the go and managed to make reebok's zigtechs weep in less than a year. She loves her pink adidas! They look adorable on her. Very well constructed. They are true to size. My advise for parents with growing children is to buy these sneaks a half size bigger to make sure your child gets more than six months worth of comfortable wear. I'll be giving an update on these sneak's quality after six month to compare with reebok's zigtechs. After six month of wear is when her zigtechs started falling apart.
