Loooooove these boots!  They softly hug your legs with a really touchable velvety suede synthetic material.  They're true to size for me, and surprisingly comfortable.  Some over the knee boots seem to forget to contour the leg.  These ones are deliciously slim and soft, so the boot almost feels like a second skin.  The material is softly giving too, so there is a little stretch in the calf if you need it.  And the black studs are really nice quality.  They almost look like Swarovsky crystal.

RECOMMENDATION:  Go for it!  They're definitely worth the investment.
