Hi all, I am unsure about purchasing the Tribtoos as I'm worried that walking in them will be a problem. I have wanted them for a while and have been waiting for them to come in stock and now they have arrived. I'll have to do a mail order as I don't live near a boutique and they don't offer refunds for unsuitable items. Also, which size? I am a size 38 in Louboutin Declic and Simple Pump which is my regular size but I've heard that the Tribtoos come up large. Any advice much appreciated. Thanks!
