I think you are...
..a car wheel/tire?
I keep on walking
The movement of the wheel.
my toe is my sole
Bending a shoe's toe around to the sole will make it round like a tire.
My movement persists
When you push a wheel, it keeps on moving.
my body a hole
Wheels usually have a hole in the middle.
My neighbors support, as I support them
Car wheels work together as a team.
You could say I look like one half of ten
One half of ten is 0 which looks like a wheel.
Tree is my father, my maker a man
Earlier versions of wheels used to be made of wood. Also, car tires are made of rubber and natural rubber comes from trees.
One point to hurt me; I'm not a huge fan
Maybe a nail? Can cause harm (deflate) the car tire.
What happens above me, remains the same
What happens below me will not remain
The car stays the same while the wheels are moving but the road changes.
A maze of paths means I am good to go
The tread of a tire looks like a maze of paths. When it's clear and not worn off, the car is good to go.
The smoother the worse to keep things down low
When the tire gets smoother, it becomes slippery making the car dangerous to drive.
Do not think I'll last, even if you trust
Get a new neighbor, that's surely a must
Car wheels get changed often.
