So for work I have a chain-link fence I get to play on and my shoes, my converse,slide alot on the bar where I step on. What kind of shoes would be better for not slipping off and fall on my butt? My friend told me to wrap a piece of duct tape around them and just take replace it every night. But I think that would make them more slippery. Another person recommended nurse shoes. Would those even work and if so where could I get them and how much are they?
