is great for used equipment! Buy her whatever works for your budget. Nothing worse than spending more than you have.. I think it's good for kids to learn that we all have to live by the numbers we have.
I got my first pair of brand new riding boots for my birthday but no way am I walking through horse poop and mud up to my ankles with my fabulous new laramie snake skins. I'll use them when the weather's better, but for now I'm using my preowned steel toed durangos for riding. (they're half real leather and half leatherette or whatever they're calling make believe leather this year and when I have to turn out my horse and it's wet and muddy and nasty, I just do what I have to and that's that.)
Oh PS...I got my first pair of paddock boots on ebay, in gorgeous condition. Really flashy too - brown and navy leather and they cost about 40 w shipping. I also got my half chaps and I wear wide calve and I got them at a great price. Do not underestimate ebay for great deals. Set up your search and save your search and they'll email you when something comes within your parameters.
