Something I’ve always wondered: do pros actually ride Footprint, Remind, etc.? I know they have their teams, but do actual respectable pros and not Joey Brezinski really go out of their way to buy and use them? If so, you don’t hear about it and makes me wonder if it’s all smoke and mirrors.
I am sure there are people of all ability levels (including pros) who will pay good money for anything, but more often than not my experience with any pro or on their way to being pro type of skateboarders is more the other end of the scale, as in they will rarely spend any money on anything and take whatever they are given and just make do with that, for however long they can. Not to go as far as to say, many just don't have money to spare like that, but there is very much more a product package sent to a lot of people from whatever companies that may not be on said pro rosters or teams, but enjoy the benefits of these packages through friends, hook ups, mates, whatever other deals, etc.
Regarding any product, including insoles, if they get it for free, they will ride it and use it, no worries. If they don't like it or can swap it for something they do want, then they will do so where ever they are able including their local shop spono or anywhere they might go on the road, or just sell it, give it away or whatever.
Not that often will they change out things very specifically like insoles unless they have to for whatever reason, or they are on said insole brands and get them all for free, but I am sure there would be some out there who would swap out stock insoles for something a bit better for their own feet, that the general public would never know about.
