I am a woman with terrible foot problems--broken feet from horse's stomping on them and bunions--and I have to wear a men's size 7-4E. These are the most comfortable boots I have ever had and I am extremely picky about shoes. I did have to remove the insole that was in them--it was nonsupportive and too narrow for the boot. However with some good insoles these are the best Danner's ever; they are also without a lot of insulation so I anticipate they will be fine in an Oklahoma summer. They run true to size; maybe a slight bit larger than most 7-4E; construction is sound.
