Designer shoes are a long term investment. God is in the details, and a good quality, well-made pair of shoes are one of the things that can elevate your look.
If you're the practical type and do not want to over splurge on shoes, you can invest on just a few key styles.
1) Ballet Flats (Lanvin or Ferragamo)
2) Low heeled pumps (Louboutins)
3) Flat Sandals (Tory Burch? Depends on your style).
Timeless items that you will wear over and over again on a daily basis. Other styles you can look into are moccasins from Tod's or low wedge sandals from Stuart Weitzman.
I'm in my early twenties, I own designer classics that I take care off and hope that they will take me through my 30s and beyond. I appreciate that the shoes are made fully from quality leather and the last is of a good fit. I am more likely to buy seasonal trends from high street stores such as Zara and Topshop. But even so, I do still try and buy shoes that are made from leather.
Hope that helps
