I highly doubt that. Pero, sin miedo, hay que desplegarlo hasta que la pata quede alineada con la placa de metal curva (como se ve en la foto). My knees don’t hurt with these like they do with shoes that have more heel. Be careful when buying this, and take that into account. I had been wearing quilted slippers and they would not hold up for any length of time, these slippers are so well made, and comfort is NOT slighted, that I look forward to wearing them for some time. This is a gift to my wife, she is really happy with those sandals. From the quality of the visibility the mirror provides to,the metal of the frame and mounting hardware. I wanted to love these with a solid 5 stars based on their looks, but I just cant based on how theyre made and how they feel. Let me set the scene that is my 35 year old face. They are comfortable to wear and the hard shell carrying case keeps them safe when not in use.
