★ The Columbia walking shoes I bought in Hangzhou are broken. Can it be repaired in Shanghai?

Even if you talk to your brother in Hangzhou, if it can be repaired, it may be sent to Hangzhou or an agent. If it is serious, it may be returned to the domestic factory, but it will generally be handled like this. It usually takes about a week to repair. If you know the phone number of Hangzhou store, you'd better communicate with them first. It's a regular shopping mall, no problem. I tried your situation, but it was quickly solved. This is mainly a matter of time. Don't worry. Remember: don't try to repair it yourself. If there is any problem, you can't say it yourself. The texture of walking shoes is very hard!
