Stretching my Pleasers

Hi ladies....maybe you can help me loosen these babies up 😂 I usually wear a 7.5 or an 8 but these were 7s that were brand new with stickers someone had bought and was selling on ebay for $20 so i figured guess I'm trying a 7 😂 They're ok in length, but they're the standard peep toe pleasers and they are just too narrow for my beefy toes. My little toes actually get forced to curl under and as my grandma had horrible feet in her advanced age I'm not looking to get hammertoe 😲 . I'm trying to figure the best way to get some more width out of it...I think I would have to use some heat to get them to widen the extra 1/4"-1/2" I want because they just don't seem to be stretching enough with my feet alone, and any stretch I do get out of them disappears if I don't wear them for a few days. I don't want to have to wear them everyyyy day to get them to stretch. I'm more of a barefoot person 😀
