The bottom hard rubber part separated from the rest of the sandal. Especially God for removing tree pollen in spring and summer. This doesn?t fit my car. After months of wearing flip flops in this heat my feet have been hurting. I would say these area bit small made and advise at least one size bigger than your usual. Well packed. I use them in my Ipad pro as well and certain phones you can use them that still take an earphone 3. Footbed is stiff but will give it a chance hoping it will soften up as I wear them. So convenient to just slip on and go and slip right off at home. Now the vest was a little hard getting on, I had to have my husband pull it down for me.
