Well bro, it depends how hard you are on them...I have a pair, and ride about 4-5 times a week and there is no way that mine are going to last the full season...all I do is rails so that's obviously the problem, but you should get them to last the season.
That being said...they are the sickest most fun skis to ride ever though...those butter zones are A-M-A-Z-I-N-G!
Have fun!!!!
