give them time
Best sandals I've ever had. They are rugged enough for day hikes and cute enough to wear with a casual dress. It took me quite a while to get the straps adjusted and to get used to the footbed but once I had it right the sandals were awesome and I can wear them all day. I haven't worn my Keens once since getting these. The ZX/1 is cuter and more comfortable. I did order a half size down from my regular size and I'm happy with that.
