I love this pair of shoes so much I purchased them in green and pink. It ran a 1/2 size small and true to width for me. I am not experiencing the blistering that others have described. I purchased a slip guard to prevent me from sliding forward in the shoe because of the heel height. I would recommend if the heel height is too high and pushes you forward to the point of blistering, take them to a shoe repair shop and have the heel shortened. I have done this with several pairs of my extremely high heels and it really takes the pressure off the ball of your foot and prevents you from sliding forward in the shoes. I can't wait until next summer to wear these shoes. I am going to wait until then to wear them and continue with the color blocking trend!
