When I see shoes I like I buy them, and eventually I realise I can't walk in them
Most Helpful Girl
I shop for high heels all time and here my tips;
1. If your big toe is less than a thumb space away from the end of the shoe, it's likely too small.
2. If it's acting like a flip flop and you constantly have to readjust your heel, it's too big.
3. If it's cutting at the back of your foot, that can mean it's either too small or too big.
Hope I've helped ;)1
