Query: Small, wobbly, not very durable

These spaces don't really provide for much "spacing" as they are quite small and squishy. They will only space your toes apart <1/4 inch. They are soft, but the softness compromises the durability, as the vertical sides seem to "flake off" from wear. They are very comfortable and sometimes I forget I'm wearing them, but be warned that they will not always stay in place very well and they will last maybe one month before they begin to flake away.
