I want to buy some running shoes . Maybe New Balance .   Why do you need running shoes ? You aren't a runner .   But I exercise at the club . And I use the stepping machine.So I need good running shoes .   That's not the same.Maybe you want to buy running-shoe-style shoes , but not real running shoes .   What's the difference ?   There isn't much difference . But there is some difference.For one thing , real running shoes are much more expensive.They have very lightweight materials.They ' re designed for serious runner
