ankle Fracture 1 week post op problems with my boot too lose

Yes, take it off.  Get a stretchy cotton sock a diabetic sock and cut the toe part off so you can see your toes.  Lie down on the opposite side of the injury and support your foot on a soft thin pillow.  Take whatever medicine for pain you've been told to take.  After it feels better you can put the boot back on.  The boot should never feel too tight. Let your doctor know what's happening.

I found that my foot felt that way for a few weeks any time it was dependent after surgery. For me, it wasn't so much the boot being too tight (because mine had Velcro) as it was just the awful swelling happening having it below the heart. It would also turn purple as well, especially in the shower. It does go away it just takes time. You said it has been one week and I hate to say this but that's not very long in the scheme of things and you should probably still be elevating most of the time. You can take the boot off when you're not ambulating. It sometimes helped to just have my knee bent while getting around just so it wouldn't have all the blood rush straight down. I didn't spend too long upright and I healed fairly fast. I hope it gets better for you.

i am concerned that the boot is loose  around my foot thank you for your response 

Hi RamaLit! I hope things are better for you today.

If I were you, I would take the boot off, elevate your foot and ice it as often as possible. If that seems like a lot of work, I think elevation is the most important.

 A doctor may have some advice and put your mind at ease.

Here's hoping that you have a speedy recovery RamaLit!

I hated the boot caused me so much pain. I only had it for a week and a half. Surgeon said not to use it as it was for support and should not cause pain. I’m a tough old thing but that thing had me in tears. And if you don’t wear an Even Up Shoe with it will cause a lot of secondary injuries. I’m  7 months on now. Still have good and not so good days.
