They are without doubt THE most comfortable boots I have ever owned. A bit of advice I would offer is go try several different boots on, I tried about 5 or 6 different makes, but the minute I tried on the Asolo's I knew they were the ones for me.
Edit: just read your budget, these can be picked up cheaper if you shop around.
If anyone ever talks about walking boots of any sort I cant sing the praises of Salomon boots enough, my current pair have probably done about 1000+ miles and still going strong. Best boots I have owned bar none.
