How Wide are Merrell Hydro Mocs?

As I discussed earlier, my Merrell Hydro Mocs do not fit as wide as my Crocs. Crocs are well known for having a wide, roomy design. Even though my Merrell Hydro Mocs don’t fit as wide as Crocs, I would not describe them as being narrow.

For Merrell Hydro Moc width comparison, here are men’s Merrell Hydro Mocs compared to Crocs:

merrell-hydro-moc-vs-crocs-sizing

And here are women’s Merrell Hydro Mocs compared to Crocs:

merrell-womens-hydro-moc-vs-crocs-sizing

In the photo below, I tried to get a better representation of exactly how much wider Crocs are than the Merrell Hydro Mocs. If you look closely, you can see that the Crocs (on the left) are a little bit wider than the Hydro Mocs (on the right):

For more Merrell Hydro Moc width comparison, here are my Merrell Hydro Mocs (in standard width) compared to Nike Air Monarch 4E Extra Wide shoes:

merrell-hydro-moc-vs-nike-air-moncarch-sizing

The main takeaway is don’t expect Merrell Hydro Moc sizing to be narrow, but they do not fit quite as wide as Crocs.


Merrell Hydro Moc Size Measurements

Height

Below is the height measurement of my size 12 Merrell Hydro Moc shoes:

merrell-hydro-moc-height

Weight

My size 12 Merrell Hydro Mocs weigh 0.60 pounds per shoe. Here I am weighing my shoes:

merrell-hydro-moc-weight

The Merrell Hydro Mocs do feel very lightweight on my foot, but it is fair to point out that I did find Crocs Classics to weigh less. My size 12 Crocs Classic weighs 0.43 pounds per shoe:

crocs-classic-weight

The Merrell Hydro Moc is a lightweight shoe. If you prefer a sturdier slip-on shoe, perhaps the Merrell Jungle Moc would be a better option.

Heel Type

One feature that makes the Merrell Hydro Mocs unique from Crocs is the heel design. The Merrell Hydro Mocs have a heel “sling” that Crocs Classics do not have (Hydro Mocs on right):

merrell-hydro-moc-heel-vs-crocs

This may allow the Merrell Hydro Mocs to comply with certain workplace standards that Crocs Classics do not.

Comfort

One thing I really like about the Merrell Hydro Mocs is I think they provide more cushioning under the foot than Crocs. I feel a softer compression under both the toe pad and the heel.

What Size Should You Order for Merrell Hydro Mocs?

In my experience, Merrell Hydro Moc sizing is true to size, so ordering normal sizing is my recommendation. If you normally wear a half size in Merrell footwear, Merrell suggests on their website that you size down the Hydro Mocs (source). I would agree with this. I think if you sized up, they would likely be too loose in length.
