All three may be nice shoes, however I’ll say “you get what you pay for”. At the decrease end of their spectrums, Ferragamo in all probability get the nod for me however none of them fall into the zone of being high quality sneakers.
Id say overall:
I have not bought Gucci for years, cant comment. Their kinds are often fairly vomit inducing and quality doesn’t look up to the extent they set when Tom Ford was there.
I have owned several pairs of Prada sneakers, they hold up moderately well for an affordable shoe (low-cost in my e-book means beneath $600).
Ferragamo I have a couple of pairs at home, they are similar high quality to Prada but I favor them and they are somewhat cheaper as effectively.
But all three labels dont factor strongly into my shoe buying. I either like the supreme top end or the extra bottom end workhorses like AE or Bruno Magli. Cheap however not nasty shoes. I also do not think the standard of those is that a lot lower than above 3 labels. Avoid mid range, gravitate both in direction of the more backside finish or top finish.
