Hi Everyone, this is my first post. Happy holidays! I've been lurking here on and off for a while and have finally decided to post. I have a pair of boots on hold in size 8. I'm usually a 7.5. Just wondering how the sizing on Coach boots run...big, small, true to size? Also, it's the Maxene I have on hold...I'm always weary of high boots as I have chubby calves. Are the calves tight on these or roomy? Sorry to bombard everyone with questions, TIA!
