Easy to put foot in left boot, but a struggle with the right. Bi would always buy a 9, but only 9 1/2 was available and I am glad now. It isn't overly roomy. At 5'3" these boots are a little too tall which means they are going to have to wrinkle at the ankle a fair amount. That will shorten the lifespan surely and has given me blisters. However, while riding, I am absolutely in love, no discomfort!
