It took two whole min from unboxing to sticking to the wall. I had to loosen what I had already done. but the Velcro came unstuck from the shoe. Ive worn the new slippers for 4 months and the non-skid pads have worn off the sole so they are not safe to wear on my wood floors. I usually go up a size in slides so my foot never slips off the base. I have not experienced any odour so far and have not put them in the washing machine yet. 5 but there?s very little difference. It doesn?t seem that hard and certainly isn?t something that costs much money to put the various pieces in place but to say this is a guide on how to do that would be a great disservice to the author. Love the Blue color. The soles are thick enough to protect against protrusions or abrasions.
