New leather shoes certainly look nice, but they can cause your feet to be hurting by the end of the day. There are several tried and true methods you can use to help soften your new leather shoes. One thing you can do is use newspaper to stuff them, leaving them like that for a day or two to help break them in a bit. Another step you should take is to use a good leather conditioner, which will not only soften the leather making your shoes more comfortable, but will also help keep the leather preserved and in good shape. You want to use a cloth to massage the conditioner into the shoe lightly. There are more tips and pointers available from the site I referenced below. Additionally, how you apply the leather conditioner is very important, so I included a "how to" video below as well.
