500lb chonker wants to get into rock climbing but can't find any gear made for cows

Hi there /r/climbing!

I was wondering if anyone knows what is available (if any) in regards to gear for plus-sized people, harnesses in particular.

My buddy has been climbing for quite a while and whenever he has shown me videos i have been thoroughly impressed, and last week we (a group of friends) went out to Kultur Fabrikken, which is the biggest multi-activity facility in Denmark, and watched him and some of the people he knows out there climb around, even some of our other friends climbed and had a lot of fun.

The issue is, i want to try it, but i am corporeally challenged (aka Fat) and the standard equipment wont fit me, some may say i could just start out in the boulder room which might work, but i would still like to be properly equipped, in this case it's footwear (i don't like the thought of climbing barefoot) my feet are size 46-47EU (13-14½ US) and quite wide, I've found up to size 16 but i still worry about them being too narrow (i have to buy "skater" shoes normally since they aren't as narrow)

Looks like i elegantly danced right past the fat thing, i'm a male who's 1.85m high (~6ft) and 225kg (496lbs)

i haven't found harnesses or anything for larger people so far, i might be using the wrong search parameters but i doubt it

so if anyone has any knowledge/tips/comments i'm all ears.. or well all eyes?
