Wudu and uncertainty, please help

[Street Scholar]

Salaam,

I am not sure that when I do wudu I get water on all of my skin. Particularly, the heel areas of my feet. I do my best to go over every groove but I'm not sure if I unintentionally left a spot dry.

I don't know what to do in this case...again I'm not 100% sure that every portion got wet, but do I just assume that they did? I'm worried now that my past salats may be invalid.

JazakAllah

Brother, after you wash the limb properly then if you have doubt, ignore it.

and Allah Knows Best.

If you use your hand over your feet and heels whilst the water is running over them, it is pretty much impossible for them to remain dry, I have similar issues and doubts myself but I am learning to deal with it, you can only do what you know and you attempted to wash your feet without leaving it dry intentionally.
Also unfortunately this doubt thing is fairly common and growing, [B]I just pray Allah can give us the strength to continue and ignore the doubts. Wasalaam
