Even with the Merrell brand, all footwear is made with different lasts and are going to have a slightly different fit depending on what the shoe is intended for. The Chameleon Hex is considered a multi-sport/light hiking shoe. It will have a close-to-the-foot fit with more volume in the instep. It accommodates a light to mid-weight athletic sock.

I normally wear a size 09.5 in footwear. I own a pair of ZX/2's in a size 10.0 because they are available in whole sizes only and they are perfect. They fit me well in terms of arch support, heel, and overall length.

Most Chaco's are manufactured in China as they have been for a few seaons and in regards to the sizing, from personal experience, I would try a size 09.0.

Chaco does manufacture wide widths for the Z/1 Vibram Unaweep but I am not sure about the color selections.

The Shaft of the Spirit Tibet High in a women's size 7 is 10.5" and the shaft of the Yarra for a women's size 7 is 10". They are very similar in height.

Please note the picture on the left. If you need to tighten the straps, simply reverse steps 1-4 and pull in the opposite direction of the arrows. If this doesn't work, unsticking your straps is actually a fairly simple procedure--it's just a matter of having the right materials on hand.

I use a solution of Armor-All Vinyl Cleaner and water (half and half), and squirt that down in each slot where the straps come out of the footbed. After letting that soak for a minute or two, take a pair of pliers--careful not to use the part with the teeth as that can fray your straps--and grab each strap right where it comes up out of the footbed. Using a moderate amount of force, twist the pliers towards the inside of the sandal. This should pop your straps free fairly easily. Please do not twist so hard that your hurt your wrist or tear the footbed of your sandal.

The ZX/2 does come in medium and wide widths but I am not sure what width it is for this site. To determine the width, the back of the heel on the sole symbolizes what width the shoe is (dots or hyphens). For example, if the back of the shoe says -7W- it stands for a Womens Wide in a size 7.

The Pro series is a marking sole whereas the Unaweep is a non-marking sole. The Pro is specifically designed for outdoor professionals who require an anti-slip compound that holds on wet rocks, root filled trails and steep climbs. The Unaweep is more casual but still is a combination of slip resistance and traction.

The difference between the medium and wide is that the wide is approximately 1/4" more than the medium across the ball of the foot and is also slightly larger in the heel area.

The weight is about 3lbs. 8oz. for the pair.
