These shoes basically come with interchangeable tops, so you can get more wear out of each pair by changing the way the top half looks. There are all kinds of different soles and tops to choose from, from flip flops to these sort of heels I have here.
I think it’s cool as it means you can take one pair of shoes on holiday with you, plus a bunch of tops for them that pack up quite small. Then you can just swap them round to go with your outfits.
Here’s what the bottom bit looks like without a top.
As you can see, the tops clip onto those bits down the side. I’ve not tried them myself to see how strong those bits are. They’d need to be quite strong clips to keep the top on through heavy use!
