I thought you already had a blue pair Sian! No need to be sorry, we all fit differently in any footwear! I got my normal size and they fit true to size, I did try a size smaller as heard they ran big - but that's a load of rubbish!
Yeah, I got the bronze as wanted a colour that no one had and also favoured the darker coloured sole. Apparently my bronze ones look like gladiator sandals when I've got them on - due to the colours!!!
Anyway if you can get them to fit you properly they are amazingly comfortable! And great walking shoes for thongs as you can actually walk fast in them without them coming or slopping off your feet!
Sorry - didn't feel comfy to me as the ball of my foot wasn't in the correct part of the sole - think my toes are short and fat like my fingers! Hence the squishy bits weren't in the right places! But if they'd fitted I'd already have a pair! May try them on again sometime as they look lovely - although I want the blue ones!
