True to size and very comfortable.
These have been a great buy, I wanted something comfortable for a trip to Rome. We walked pretty much all day for 3 days and these were perfect, comfortable and didn’t end up rubbing as much feet stayed pretty cool in them. They’re correct to size as well so you can order your normal size. No worries about laces coming untied with the toggle, I really like these. More colour ways needed.

Exceptional quality, still figuring out the lacing
Very comfortable. The interior material is better than standard UB models. The lacing is unique but not sure how it would hold in heavy use. I bought these for casual use so no issues.
