I am a man that is aroused by men's feet. Does that mean I'm gay?
Everyone is different. No matter how you define yourself - gay, straight, bisexual or whatever, if you are turned on by male feet, enjoy! There's absolutely nothing wrong or dirty about doing so.
Aren't men's feet disgusting?
Male feet are no more or less "disgusting" than any other body part. The general cleanliness of any man plays a role in how clean any part of his body is. While feet are prone to abuse and neglect, with a regular degree of care, they are as clean and healthy as any other body part.
