Why would someone buy a $30'000 Harley and then add a 3rd party air horn ("fix") to the bike? Safety perhaps? I know you're coming in to the conversation a bit late...but I'll state it again...I live in a rather hilly country where rain and snow are not uncommon...so my choice according to you would be to buy crap shoes...or slide down the side of freakin hill? What about respecting the construction of my $2'000 suits and overcoats? Do you think nice long scratch down the side of my shoes would look better than a toppy?...
And again...If I was paying $1'500 for the shoes and had a choice of sole, I would go that route...I am not paying $1'500 and am therefore limited to the available stock...Would you have a better solution other tthan shipping new shoes to the factory for a completely different sole?
Actually, I'm not coming to this discussion late at all (if you're talking to me)--I've been here a long time (sometimes it seems forever) and I've been making this same point forever.
FWIW, I grew up in snow country. But I lived in a two tier rain forest for a number of years and wore leather soled boots every day. Still do. I currently live in country that gets snow and ice throughout the winter months. Never needed or wanted topy even though I was up on an inch and five-eighths heel. But, if it means anything, my wife and I took dance lessons and I learned to carry my weight in such a way as to make graceful recoveries...if not the walking itself...more likely. In my life, I've slipped more times with rubber under me than with leather...ostensibly for the same reason as rubber is near onto useless on icy pavement.
As for better solutions,...yes, having the shoes made with a full-on rubber outsole seems a more focused and mindful solution than Topy. Traction (such as it is) is as good or better and you'll save even more money.
