We all know Birkenstocks are just about the hottest footwear on the high street this year. The world can’t get enough. However, if you’re looking to rock the trend with a bit more flare, may we suggest these beauts from River Island? The strap is leopard print calf hair and adding another texture to the game, we have some jewel-adornment happening. Work them with boyfriend jeans and a simple tee for a casual look. Or, why not try wearing with a summer-print dress? So many options, so little money. {River Island Leopard Mules £45}
