I have had 3 ankle reconstructions, hammer toe, 5 knee surgeries, hyper extended a achilles tendon (cast for 4 weeks), blew-out a peroneal tendon, tore a calf (3"by 5" tear). Many caused by men's shoes not fitting the shape of my feet. Only the peroneal (road pavement gave way) and calf (skiing) since I switched to only women's shoes.
@mlroseplant I have a friend who has had both knees replaced. And he still hikes and I have meet people on the slopes who have had knee replacements. If you wife waits too long, then she could do too much damage that can't be fixed.
