Hi @maggiesimmons - Thanks for waiting while we found some more information for you on these!
We do not have plans in the short term to carry the Oboz Bridger Mid BDry Hiking Boots in a 10.5 wide, but we do have the option to special order through Oboz. To do that, you will have to contact your local REI and ask if there is special order availability in those boots in your perfect size!
The Bridger 9" Insulated Waterproof Boot is also available currently in a 10.5 wide, though it is a winter specific boot for cold weather hiking and snowshoeing.
None of the other women's Oboz Bridger models are available in that size from REI.
Hopefully this helps. We hope you're able to get your goldilocks fit sooner than later!
