We visited the shop slcku.com
Analyzing the web we see that it does not have SSL. Looking a little more we see that it has icons of social networks that do not point to any profile. You can only pay by credit card. We can’t find the information of the company behind the web anywhere. And on the subject prices because we see shoes worth more than 60 € here are sold for less than 20 €. So we are dealing with a fake shop and a scam.
