Some shoes must come already with the choice for the coustumers likes if they would like to have some rubber soll to be adden and quality hill or ( hill with the metal bracket) like I show you in that picture . Because every coustumer if he buys good quality shoes they want them first last long, secondly looking always good and most important is the safety , not like you wear new shoes and gone to the resturant and on the dance floor you became like that high jumping woman Elena Isinbaeva and look stupid front of all resturant. The new shoes with the plastic platform I can go play ice hockey is REALY that sleepery espesaly when you walking in this new laminat flooring and in parket flooring to. Any way I hope my advice will help to improof the shoe making industry.
