I have never charged a person for molding a snowboard boot. You put it on a glorified hairdryer, wait, have them put it on and lace it up tight, make them walk around and LOOK AT ALL THE PRODUCT IN YOUR STORE, then done. Why charge for that, no "service" was actually given as I didn't actually do anything. More often then not they find something they want to buy too.
If you really can't find a shop anywhere that will do it for free and REALLY want to mold them, take the insoles out, blast them with a hairdryer for about 5 minutes on low or medium (not high), lace up and stand/walk for 15 minutes. Snowboard boots are a lot less finnicky than ski boots. Molding doesn't take any expertise as it does with ski boots.
Thanks for not charging people. Good boot fitters are hard to find.
I only disagree that for some people, they need more time and work on their boots.
Also, walking around when liners are hot might not be the best thing IMO. I like to do mine with my ankles/knees flexed and try to stay still, or just flex. I got more than 45 days out of some salomon liners that were done this way.
