Looked at new pair of Sperry Topsiders the other day. The sypes, cuts in the sole that make them sip resistant, are very shallow, not like the deep cuts in the older shoes. Seems like they are buying
into planned obsolescence hoping you'll quickly wear the soles down to where they are no longer slip resistant. Quit buying
Topsiders many years ago because they don't fit my fat feet. Have a pair squirreled away in the closet will have to check out the soles for hardness when I get back home. Know that I had a pair of West Marine
boat sole sandals that did harden to the point that they were slippery on concrete
Have tried Crocs which work okay if you don't get them wet and replace them regularly. Like the protection of the enclosed toe but my feet sweat in them and need to wear socks in hot weather
. Once you get them soaked, the interior
sole is slippery, lets your foot slide around and they make a squelching noise
as you walk around. On wet surfaces, once the soles are worn, it's safer to walk on ice.
Have switched to cheap
Keen knock off sandals that are inexpensive and comfortable to wear.
