Will frequent sliding while wearing socks cause noticeable wear and tear on hardwood floors over time?
Nothing short of laminating it in acrylic 3" thick and never putting anything on your floor, ever, is going to keep it from getting some damage eventually.

If you find the proper stain color, practice a bit matching the color, and learn how to refinish the floor, you needn't let it worry you too much.  Hardwood is extremely resilient and eminently restore-able - even bamboo can be reclaimed and restored to beauty.

I refer you and your no doubt lovely and certainly conscientious wife to this example of how good a really ugly floor can look (written by yours truly...)
