The fit is very, very tight. You should buy a size higher i.e. If your normal shoe size is 8,you should buy size 9 of these shoes. The material quality is bad - the lace is so cheap material that even the roadside hawkers have better quality shoelaces and the mesh at the top is very slim that I wonder if it can last for a month! The only decent thing about these shoes is that they are lightweight.
To summarize, don't buy these shoes. It is a waste of time and money.
