I bought two pairs, brown and another brown. Comfortable as can be, look good, but they delaminate pretty quick. The outer sole falls off.

All 4 of mine started peeling at the sides, then the whole sole fell off. The shoe shop glued them back together; a month later they began falling apart again. I glued them myself, using barge cement. Nothing better for shoes. But not even Barge could keep these from falling apart. Nor can Gorilla Glue which is what I tried next.

So I tried epoxy, an epoxy formulated for rubber. It held for a month or so. Then the soles on that pair split in pieces and fell off. They no like epoxy.

The outer sole is a composition called "Spider Rubber" that evidently resists ALL glues. If there's a blacksmith in your area, ask him to nail them together.
