The items I ordered were shipped and received promptly.  Unfortunately, I had ordered the wrong size, my shoe size [10] being on the border between LL and XL.  I contacted their customer service and arranged replacement with the correct size; I found their customer service to be very helpful in getting the best size, XL in my case.

I have owned Okabashi slides for many years; they are tough and they give remarkably long service; quality is excellent for the price.  I now own 3 pairs of them, and I wear them for a lot of my leisure time, including in gardening and light outdoor work.
