I typed this up like three hours ago then my internet crapped out, but,
All mah winter boots are sized enough to fit my foot plus a wool sock, so I used to get that problem too, when my foot drifts up and down too much in the boot. The insole is a good idea, but all I had to do was lace them tighter when wearing regular socks. Maybe you could try that?
Patrick, dog, I am going to be harsh here and say maybe the problem is you? Like, I'm not trying to shit on you but you have lots of complaints, it seems, about people problems where people don't like or appreciate you. I do not know the situation I do not know the people, but, like, look back over all your times with these 'friends' and try and think if you've been reliably a good person to be around.
Jeph's advice on posting here, or anywhere, was "Is this something someone else would want to read", and I used to take that to heart a lot. Obviously, I think of that less so now because often I'm just making silly conversational remarks to people I know, but you can apply that sentiment to real life. Are you saying things these people enjoy hearing? Are you stimulating and enjoyable to be around? Do you hang around them too much? Are you coming on too strong? Do you make jokes or say things you think are funny, but they just give a light chuckle and disregard? There are lots of possible reasons for why you keep seeming to be having bad things with people, and you are a common element to these problems. Self examination is really useful. I personally found it really irritating when people would hang around my place of work all the time if they kept using the same shtick and jokes and kept asking 'so when are you hiring' all the time. Some of our regulars were great people and I keep in touch with them to this day, some of them I had no time for and if I met them on the street I might just tell them to fuck off if they tried to engage me in conversation, though I always was polite & quiet to them at work.
Like, what I am saying is, look back over yourself because even if they are all dicks and you are a paragon of humanity, reflection is super useful and maybe you will learn some stuff.
Also, in times of slow business (winter time) sometimes bosses do take time to get around to you because they presently have staff and don't want to spend more money right now. Alternatively, running a business can be a bunch of work, so maybe the problem there is that the people don't have time or aren't organized enough to train you right now, and maybe fortunes will be better in a week. Don't get angry or arrogant with them though, life is tough for everybody a lot of the time.
