Need advice and help on this

If they work for your feet, I wouldn’t give a damn

 

If it’s bad to do on NoFap it’s bad to do not on NoFap. NoFap is here to help you live a better life, not issue you a list of arbitrary rules. But sure, cross dressing might be fetish territory, in which case I would advise pumping the figurative brakes on while you figure out how to un-pornify your life.

Whether wearing these shoes would be cross dressing, though, is another question. My guess is they are designed for narrower feet, so they work better for women. On the other hand, as the saying goes; “If the shoe fits, wear it.”
All cultures have gendered dress codes, but running shoes are relatively gender neutral in both form and function. You didn’t notice they were coded for women until you saw the label, so I’m assuming no one else would know unless you told them.

However, and this is the important part, if they are designed with female feet in mind and won’t function as well on your male feet, as @cyberman suggests, you should switch.

 

To tell you the truth, nothing is built to last these days. I was talking about the same thing with my colleague yesterday. I wouldn't waste more money on new shoes just yet, but I wouldn't go back to that old brand either.
