    Great for hiking

    Have used these all summer long for hiking around the White Mountains and Maine and Vermont. Love them. Fit is good. Never too tight and never too loose. If you prefer a tighter fit then you will want an extra tech strap.

    New sandals

    This is my second pair of Luna’s and couldn’t be more stoked. Sized down from the last pair and made all the difference (even though I wore the old ones through). Haven’t taken them off since!

    cool running is that!


    Great sandals! Great customer service!

    Love my sandals. It took me a couple of years to finally purchase a pair. I almost exclusively wear them over my other slip-on sandals now. I did notice some hot spots on my feet the first week or two of wearing the sandals but once they broke in and my feet got used to them I can wear them all day with no issues. I love having the tread on the soles. I was on the fence after I ordered them if I would like the tread or not. No regrets after the first couple of uses. The customer service was excellent. There was a little issue with my order. The shipment got stuck in the warehouse and took a few days to get out the door but the CS team did a great job of tracking down my sandals and ensuring that they made it to me. The also went out of their way to follow up with me throughout the process.



    Awesome ... just the straps are a bit too long for the size of my foot, have to tuck them back twice.
