Theres a horror game on Steam called blasphemous that is based on Spanish / Gothic Christan stuff about sin, flagellation and penance.
It features several references and shows feet being kissed and worshipped in the most unbelievably artistically and true to such religious practices of old. League of barefoot walkers / some false deity whose followers would wash and worship his feet / kissing feet to cleanse sin.
That's already gone way too spoilery, will add a screenshot in a bit.
Ah this is relevant:
