Kid's canyoneering/climbing stuff

I have some kids climbing and canyoneering stuff that are too small for the kids. What do people usually do with it? I could give it away to those who are interested. I'd rather do that then give it to the second hand store and have no buyers.

Does anyone have a need of harnesses, noprene socks, and canyoneering shoes, for a 5-8 year old?

Pick me, Pick me. I have a daughter that would be in that range to use.

If you have extra I could use some as well. I have three in that age range.

Any suggestions on canyoneering shoes for little ones that age (8-9)? Preferably something that has been tested in canyons with swimmers.

Zion Adventure company sells used 5.10s outside their door. I picked up a pair or two for my kids, still in good shape. They have worked well.

I didn't realize the 5.10 Canyoneers came in sizes that small. My 9 year old is a size 4.
