How long do boots and half-chaps last, on average?

I've had my ariat paddock boots.. for... ummm 4 yrs i think... and they are still going strong... mind you i clean and oil them never once a fortnight... and i wear them pretty much every day... i have a pair of ariat 1/2 chaps... that i only wear when i show... prob what 3-4 times a month and i've had them for about 2 years and they still look like new... but i clean them after every time i use them... i have some ariat boots that i show in and the same is with them... 2 yrs look like new but i clean them after ever show... i think the more you look after them and oil them to keep the subtle the less cracking and wear you will have so the longer they will last... the heal and sole does need to be replaced on some of the ariats after awhile as they wear alot quicker then the leather... my half chaps that i trail and train in are just those cheap suede ones... and they last me about 8months to a year... well good luck :)
