B/W ones retail for $345. The other colors (pink, blue, green,yello) cost less, I want to say $295 but I am not 100% positive.
My personal opinion - they are not meant for a lot of walking, they have very little support and will get slippery when feet get sweaty between the foot sole and insole of the shoe. I passed on those bc. my experience is a thin plastic sole like that will burn your foot sole from rubbing after too much walking on a hot humid day or when walked around hot sidewalks. To me they are meant for fun quick outings, poolside, beach, a cruise. I think they can be worn with dresses for a summer party, they would look adorable, but again, my opinion, they are not meant for a lot of walking.
