Query: Clarks Artisan Coreen Wedge are dangerous shoes

I am writing to warn women that if they wear Clarks Artisan Coreen Wedges, they should be very careful regarding the ankle strap. It velcros down with no room for adjustment of tightness around the ankle, meaning if the ankle strap is at all loose around the ankle, the foot is not stable in the shoe. I have these shoes in tan and in black, and even though they seem to be made very well, the ankle strap is dangerous. I twisted my ankle while wearing the shoe, and ended up with a severe break of two bones (fibula and tibia) in my ankle. I feel that the shoe was the cause of my twisting my ankle because the ankle strap cannot be tightened. The velcro on the ankle strap has to fit exactly over the other side of the velcro on the shoe itself to close properly. If the ankle strap was adjustable, the shoe would be a great shoe. But beware! I had to learn the hard way.
