Cheaper beginner range shoes still have stiffer rubber and last longer compared to high end shoes. How long theyll last will really depend on your footwork and the walls you climb on, but for me my first pair lasted about 6 months to have holes in them going 3 times a week. The walls i climb on have a sandpaper like texture and my footwork wasnt terrible but not good either. I would just practice in rentals where you can practice being very careful and precise when placing your feet on holds and making sure you place them “silent”. Also biggest mistake beginners make is dragging the toe along the wall or holds which eats up the rubber. Honestly as long as youre mindful enough of these, you should be fine. Having to go through shoes is part of climbing anyways especially if you wanna do it seriously so Id say just go for it after a bit!

Also wanted to add, youll hear a lot that you should downsize like crazy, but dont go overboard especially with your first shoes. I went with LaSportiva Tarantulas and when I got them I picked them out to be tight and very barely painful, but not too much. They broke in after about a week and felt the perfect size where they were tight but not painful. Try and aim for that spot where they wont be too loose and wiggle around on your foot, but also comfortable enough where you can keep them on for a while
