Wear them. Really wear them.

Take your LUNAs out for 30 days and use them the way you actually will. Trail miles, river crossings, the walk for coffee, a whole day on your feet. Get them dusty, get them wet, put real ground under them. There is no mileage limit and no keep-them-pristine clause.

If they turn out not to be right for you, send them back within 30 days of delivery for a refund, no questions asked, however worn they are. Want to try a different model instead? Return shipping is on us.
