These boots run true to size. I normally wear US 10.5D boots, and 10.5D 2990s fit quite well.

For women's sizing...

The 4D 2990s should fit someone who normally wears a woman's size 5.5D boot, and possibly someone who wears a woman's size 5.5B, or 5D, after putting in removeable footbeds.

The 4.5D 2990s should fit someone who normally wears a woman's size 6D boot, and possibly someone who wears a woman's size 6B, or 5.5D, after putting in removeable footbeds.

The 5D 2990s should fit someone who normally wears a woman's size 6.5D boot, and possibly someone who wears a woman's size 6.5B, or 6D, after putting in removeable footbeds.

It's worth mentioning all 2990s posted here are factory 1sts.

Posted below is a link to various Red Wing Shoes care products I have available. If anything else is purchased within a few hours of buying the boots, I’ll be able to combine the orders and ship everything together. If the link doesn’t work, search for ‘Misc care’ on my store page and the listing should pop up.
