I have done what I usually never do and bought a pair of boots even though I know they're snug across the width (which is also unusual as I have narrow feet).
They're leather, which is why I've decided to keep them and try to just ease them out where they're snug, if that's A Thing I Can Do. They're not lace-up, so I can't alter the width by easing out the laces. They're just a plain low calf-height biker boot.
My plan is just to wear them around the house with a thick pair of socks until they feel easier.
But are there any other things I can try, if that doesn't work, or if there's just a better/faster/more likely way?
Pleeeease don't tell me I should return them (which is what I normally do!) - I love them... I've returned shoes regularly for being too short as I feel like length is hard to alter, but instinctively I think you can make them a little wider...?
