SSH jumping over socks(4/5) proxy chain. Host -> socks proxy -> socks proxy -> destination

I got a great answer for my previous question about connecting from Machine A to Machine C via Socks proxy located on Machine B.

Say Machine B Ip is 218.62.97.105 and it is listening on port 1080

The command for that:

ssh -o ProxyCommand='socat - socks:218.62.97.105:HOST_C:21,socksport=1080'

I wonder if it is possible to make a chain from the socks proxies.

Consider scenario: Machine A -> Machine B (Socks proxy 1) -> Machine C (Socks proxy 2) -> Machine D (destination)

Machine B IP: 218.62.97.105 PORT 1080

Machine C IP: 11.11.11.11 PORT 3128

Machine D IP: 55.55.55.55 PORT 8080

I hope there is someone out there experienced with socat or any other tool as it seems pretty complicated for me at this point.

+100 for anyone who could give me the working answer.
