I walked past Topshop the other day and saw these metallic sandal wedges in the window, which would carry through nicely from spring to summer.  I like that the heel isn't too much of a mega fall-over wedge - in fact they're almost like sensible flatforms - and the simple 90s thick sandal straps.

My problem is that I also need want these sports luxe trainer wedges (and I'm not allowed to buy a fourth pair of shoes this month...) which are inspired by the infamous, sold-out-everywhere Isabel Marant wedges (£430, when they're in stock), which everyone from ASH to H&M has copied.  The Topshop pair is cheaper than the ASH version and real leather as opposed to the imitation fabrics used by Hennes...  So they're probably the best high street heeled sneakers out there but I'm still not sure I want to spend £75 on trainers.  Hmm.  See my problem?
