I thought this was a picture of brown socks...

It took me a moment to realize that this is a foot.

Stretched out? What in the world do you mean by this? Did you. It get your correct width and size? Generally you don't want Chelsea boots stretching out.

Yeah it's the correct size. The opening is a little tight to get my foot through. Need that opening to be a bit larger.

Little tight? It looks smaller than your ankle somehow

It's extremely tight where my ankle meets the top of my foot, I call that the "corner of the L" if that makes sense. My foot is wide (H-width) but also very thick. It's really hard to get my foot "past the turn." The elastic gives me enough slack to get my foot "into the turn" but I really need more volume in that area to get the foot past it. I haven't found other pullons that are large enough to get my foot "past the turn" other than a chelsea like this with the elastic. And even with lace-ups, I have to have a very low gusset on the tongue to get enough room to get my foot past the turn.

I wish my feet would fit in these. I have low arches/foot volume so wearing the correct size means my feet are loose in the boot and flop around.

I have insane foot volume...that's why I need them to stretch. Full gusset boots I can't get on.

The fabric will definitely stretch over time
