As soon as you have worked out before and improved it's getting more difficult to improve and you need to pick your exercises more carefully. that's most likely also the reason why jump soles work for some and don't really work for others.
If you really want to improve your vertical by more than just 1-2 inches, then you should study some literature (e.g. vertical jump bible) and follow a training program. The key is to work on different parts of jumping (e.g. explosivness, strength, speed, etc.) only if you can combine these elements you'll become a great jumper. But it also should be mentioned that a big part of it is genetics. that's the reason why some guys jump out of the gym without any training at all.
i just started the beginner phase on VJB (both strength and plyos) and I've been working out and lifting for like 4-5 years consistently and im telling you it's not as easy as it looks. Very basic exercises but if you structure your program correctly to your body type/needs/weaknesses you'll feel instantly stronger after a couple of weeks
some great bodyweight strengthening you can do if you're "too young to lift"/dont have access to a gym
