Im always getting blisters on my feet from nearly all my shoes? - ...hard blisters on feet

Why do we always have blisters and cuts on the toes on my shoes? It's really hard for me to buy shoes, because I'm only a size of 2.5 and an adult. For example, all have any tips or advice on how or why can I do to solve this problem? I often have atleast 3 models on both feet.
