The shoes fell apart exactly one week later. Both pairs - the sole split in half. Moreover, it turned out that it was not completely rubber, but a thin layer of rubber, and under it something white like foam.
I made a refund, and the money was returned. But the disappointment remained.
A life hack for those who want to save money. You take flo shoes, wear them for a week, hand over the torn ones, and get a full refund. And take the flo shoes again, wear them for a week.... Voila!
And most importantly, the store will think about whether it is really profitable for them to sell shoes that last less than a week.
