So you want to buy a pair of $275 shoes as "beaters" to protect your $335 shoes? You realize that's only a $60 difference, yeah? And what's to say that the 1000 miles would be any more resistant to scuffs and scratches? It would seem a little...oxymoronic... to buy $275 shoes and wear them around, beating them with scuffs and all, to protect your $335 shoes. I'd suggest one of two routes:
1) Buy true beaters, like $100 Cole Haans or J&M or some house brand, and wear them out. Literally, wear them until they break then repeat. Wear the Mc's on your chosen occassions.
2) Start a shoe collection and rotation so that you don't wear one shoe so much that it is constantly berated, but rather maybe each shoe is worn once a week and the life remains less-scuffed that much longer. And be careful with your shoes. Recognize what's on your feet and conduct your actions accordingly (i.e., no James Bond chases in your AEs).
Or, just do whatever you want.
