Does Kirby wear shoes or are those his bare feet?
According to the Kirby Wiki, those are Kirby's feet:
Kirby is a small pink spherical creature with two stubby arms, two red feet, and two oval-shaped eyes with black pupils
This is further backed up when comparing against different coloured Kirby:
In general, members of the species all look similar, but sometimes have different colored skin, eyes, and feet
Given that Kirby has also been seen sleeping in bed with his red feet, I think it's a fair assessment to say that they are considered 'feet' not 'shoes':
