The Terra Fi 5 are great sandals. As with most sandals, they take a little while to break-in. But once they do, they are very comfortable and keep your feet anchored in place. The style is simple and not very exciting, but these are intended for long hikes, not fashion. The sandals are heavier and stiffer than most other Teva offerings. They are very comparable to Chacos or the Bedrock Cairns.The break-in process, unfortunately, can be very painful. Due to the way the sandals are constructed, they will do a lot of rubbing against your heels. The result can be chaffing, blistering, or something in between. It's not pleasant and it can take many days to fully break-in. This is the unfortunate reality of virtually all footwear, but given the stiffness of these sandals, it's particularly pronounced. So be prepared to have some messed up heels for a few days. But once they are broken in, it's worth it.GO DOWN A SIZE! I normally wear a size 10, but the Terra Fi size 10 was too large. Had a lot of space in front of my toes. Going down to size 9 made a huge difference. (Tevas in general seem to be fairly big so I'd recommend going down 1-2 sizes). You want the front straps just behind your toes, not covering them. Getting the sizing right is very important with any pair of sandals, especially ones like these that are intended for long hikes. You will absolutely hate the look and feel of these sandals if the sizing is wrong.The Terra Fi can weigh you down as it is intended for serious hiking and multi-day trips. They are overkill for everyday wear and most light hiking. If that is what you are interested in, I would recommend the Hurricane line over the Terra Fi. The Hurricanes are lighter and have a softer footbed, available in more colors, and is geared more towards less strenuous activities, while emulating the look of the Terra Fi.
