They stay on my feet. The right toe on the new pair feels a little snug, but i am confident that they'll be fine. The top strap is adjustable and snug enough that they fit like real shoes.

Arch hits the sweet spot and nice cushiony feel. Help keep the plantar fasciitis at bay.

They are true to size and as pictured. No breaking in needed. For me, when they are brand new, there is a break in period to make the toe material softer.

The insole is stiff and uncomfortable. Sandal is so tight across toes /top of foot that i can barely get my foot in there. Foot pad is the same, but straps are not and are quite unsatisfactory. Toe strap is scratchy and uncomfortable.

There is a top velcro strap so that helps a bit but not much. The strap is too long to catch the (attaching part) if the velcro. Quality of stitching is poor, in less than a month the strap came apart.
