I have not had any issues with the ankles of these boots at all I think they are very roomy.  The calf is fine and after a few days wear the elastic and leather does stretch some and soften up.  The purple is a true deep plum.  The fit however is strange. That is why I gave it 4 stars.  8.5 was too tight. It may have stretched some with wear. I went for 9, based on these reviews of getting a half size bigger. I usually wear a 8.5 in most keen shoes (I have 5 pairs of shoes).  These boots fit fine however they are a bit big and my heel slips up and down.  I put a heel insert in and it still slips.  It is not rubbing and painful though. Just annoying.  But I love the quality and color and I can deal with it because these boots are purple, warm, waterproof and so stylish. You can wear them under skirts or with leggings or rolled up jeans.  Have not tried skinny jeans yet but I will.  I may try thicker socks to see if that helps with heel slippage.
