Mens Gucci monogram shoes (42) 9.5

I have a pair gucci shoes with monograms, black size gucci 42 us 9.5 worn 1 time and had them in closet for a while.. Pulled out the box some time later and notice the bottom was cracking... sent back to gucci and they replaced the whole bottoms of the shoe because they didn't have this model to replace.. So whom ever purchase these shoes will be the first one to walk on the bottoms... The shoe haven't been walked on since bottom replaced.
