The answer for me is yes. Why not, there is hardly anything that can’t be bought online acturally. The shopping mall becomes fitting room for us. The same shoes could save you nearly 2/5 of money, why not buy online then? Focus on one brand you like and try the shoes style you like, remember the model number and perfect size for you, than you are ready to go, place your order online, than within 2 days, you would receive that desirable shoes with less money spended.
I have done this twice and satisfied twice. I wonder how the seller got the discount, but in China, everything is possible 
The profit of lady shoes is too large to take, even the discount shoes bought online still let me feel expensive. But there is not better choice.
Remember to buy brand shoes online, not those without any brand. It’s high chance you bought the fake if you don’t buy the brand shoes and the size would be not that perfect too. Even if there is any thing wrong with the shoes you received, you can still apply for a return of goods, so no worry at all.
of course! much better to do shopping online especially on shoes. i mean the convenience and it is actually money saving also.
