my friend did this once and mustve looked rediculous...
he took his boots, put them on, wore them to a sauna (the hot steam room shit) and literally walked in circles and like jumped up and down in there. softened and molded to his feet. thats just what he said though, hes insane.
if i were you, wear them around the house.
haha clever. Similar concept as the shops do when you purchase boots from them. They will heat the boots and form them to your feet. Downside, you have you buy their merch which means paying more than what you find online. Did that for my gf and her boots. Upside, never had any downtime on the mountain because she was in pain from her boots.
The way I see it is that I'm helping out my local boardshop/economy, plus I would feel guilty as hell after I went in the store and tried on a bunch of boots. Essentialy that's what your paying more for, a good fit and maybe a foot molding, which is worth the money.
