These are wonderful boots -I especially love the rubber sole....but when I tried them on I could only get the left boot on. No matter how I tried, the instep was too tight.to get the right boot on ..so regretfully I had to send them back. They were a little stiff  and rubbed against my ankle so I am going to try another pair . I ordered my regular size 6 -  so maybe I will try a 6 and 1/2 this time....
