Shoe size

I recently purchased a new pair of hoka Clifton 6 shoes from the running warehouse that are a size too large and I no longer have the shipping information to return items. The over size of these shoes cause one of my toes to bleed. Are there suggestion as to how I could make a better fit with these shoes so that my feet do not slide inside the shoe?

Thank you
With the start of quarantine, I started ordering things online, and for the new marathon, I also had to buy online. Usually, the sites write the insole length, but it's not always true. I have already exchanged three pairs of shoes, and it takes a lot of time. But I also understand that if I leave those that will be uncomfortable, you can forget about the marathon. I used to insert cotton wool into sneakers so they don't fall off when running but it's not that good.
