Miu Miu knee-high boots 110mm in black and burgundy leather

They are my first pair of knee-high boots in the last 7 or 8 years.  Love the chunky curvy heels and round toes.  Haven't had a chance to wear them yet because of my bump so we will see how comfortable they are.  I saw the same boots in light grey and black in London after I got these (and of course they were cheaper in London) and I am wondering whether grey would be more versatile.  It's too late now.  True to size.
