So funny story. I got these cute Topshop shoes, fab price, got them home and turns out they are man made...vegan! Which is great, except they were a scosh snug and I couldn't use my usual shoe stretch spray as it can't be used on man made shoes. So I asked google what to do...turns out you CAN stretch out man made shoes...in the oven! Put em in for about five minutes at about 150 degrees...at least that's what I did...and wear them around til they cool off...and viola!
