Now the suit is the standard for hair salon sales and other industries, there is absolutely no discrimination here, just want to show that the market demand is changing.
And sneakers are relatively comfortable and easy to wear, and now sports brands don't want to focus on doing only sports stuff ten or twenty years ago, but put more energy into fashion shoes. Reduce unnecessary functionality, increase comfort as well as fashion, respond to market needs.
After all, for some professions that require frequent walking, leather shoes are still not as comfortable as sports shoes, and it is troublesome to take care of leather shoes, which need to be wiped from time to time or even need to prepare shoe polish, or else the shoes will become dull, which in turn will reduce the wearer's taste.
