These Teva's are great for all types of terrain: dry, wet, rocky, muddy, carpet, asphalt, etc.

I own a pair of leather Teva sandals that have lasted over 15 years, but needed something for aggressive hiking not just beach and town wear.  I've been training with these for about 6 months, weights, cardio, road work and hiking.

For me, out of the box, they have fit great- no break-in period- and they're really lightweight and comfortable; however, my family grew up in the shoe business, and I know every foot is different; it's very personal and can be hit and miss when one orders a new pair of shoes.

I've had no rub or friction burns.  I have a narrow foot with a good arch and no underlying foot problems.  I wear a size 9, but based on many reviews at Amazon and Teva websites, I ordered the 9 1/2's.

In January, I tested them out with more hiking in Hawai'i at the Volcano National Park walking on lava rock; at the beach, walking out in the ocean over rocks in knee deep water, hiking the Kalaupapa Trail on Moloka'i along the Pali(or cliff)down and up 7 miles- on rocks, mud, slippery surfaces with no problems, no blisters, etc.  I wore them 24/7 while on this trip except for barefoot beach time.

They're looking good after a wash, no breakdown of material.  I love these Dozers, and I'll get another pair.  Again: every foot is different, but I highly recommend them.  Happy trails!
