I have always loved the spiked heel (which I blogged about here) they add edge to any outfit but alas except the Sam Eldeman beautifuls (Retail at around £185 but can be found cheaper)
and the various super pricey Christian Louboutin heels such as Clou Noeud Spikes (costing around the £1000 and something mark)
I had never seen a cheaper version until I went to Charlotte Russe whilst I was in California last year (of course they are cropping up in loads of places now!) I came across these amazing dupes for around £40 I think it was...possibly less.
Next I want to find some that aren't peep toe (if you know where I can get my hands on some let me know!) I personally don't find high heels with peep toe very comfortable, these however are worth suffering for. Are you a fan?
