The London boot is from the miku series of footwear by Baffin. The miku collection is an attractive luxury line of boots with all the functionality of a performance Baffin boot. We like to say, this is where function meets fashion . These boots are seam-sealed, waterproof and lined with the same Baffin b-tek insulation that we use in our polar series of footwear. Rated to minus/negative 4 degrees Fahrenheit, miku has been designed to comfortably fit a woman's foot while maintaining a tapered, slender look.
