What do you consider "budget-friendly"?
Some places like Golfsmith or Dick's Sporting Goods will sell 'last years' models at discounts, but they are still often in the $50-$60 range, about the price of a good pair of sneakers.
We just bought golf shoes for my son a few weeks ago and paid about $100, but he wears them every day and has to walk the courses (golf team in HS). A comfortable and long-lasting shoe was the priority, not necessarily the lowest price.
