The foam soles have held up great. The booties get used and they soles stay put and prevent any damage from happening. I could definately recomend the concept of using thrift store sandals and just regurlar old shoe goo. The sandals I got were foam soled, which I could cut off easily with my pull saw and trimmed with sissors and they have been durable enough to be walked up stairs. The shoe goo has held them in place with zero peeling. I can't say i run marathons in them, but they work.
I had superhuman powers, but my therapist took them away.
