That fixes my major qualm with these speakers. Supportive insole is nice, but not as nice as the Glisan model. I did both things in about 10 to 15 minutes. Even though it says 6D, it fits like a whole size smaller. I then ordered a smaller pair than I needed (a 6) and sure enough I received the correct size - a 7. It was missing parts and the glue My search brought me to the Thule 4-bike hitch carrier. First off, these sandals are totally cute and look just like the picture. I spray painted them to match the color scheme of my bathroom and used the anchors and screws to install it and it works really well and looks good to. BUT they tend to get me through the cooler/cold months before I have to replace them, which is better than most slippers you wear a lot in winter.
