The Pacific Sneaker comes in women's and men's versions. Here's how the fit differs so you can pick the right size the first time.

Quick answer

The Women's Pacific Sneaker uses the same waterproof knit Dyma-tex and lightweight EVA foam midsole as the men's version, but the women's model is built on a women's-specific last. If you normally wear a women's size, choose the Women's Pacific; if you normally wear a men's size, choose the men's Pacific. The main trade-off is fit: the women's version offers a narrower, lower-volume fit, while the men's version provides a wider, higher-volume fit. Both are unisex in style, so the deciding factor is your usual size and foot shape.

What actually differs between the men's and women's Pacific

Both versions share the same core build: a lightweight extra rebound EVA foam midsole and waterproof knit Dyma-tex technology. The difference is the last, the foot-shaped mold the shoe is built around. Women's-specific lasts are typically narrower through the heel and midfoot with a lower instep, while men's lasts are wider and higher-volume. That means the men's Pacific and women's Pacific are not interchangeable sizes; they are two different fits of the same shoe.

Because the catalog does not list separate width options for either version, your best fit comes from choosing the correct gender version and then adjusting with socks or lacing. If you are between sizes, the women's version runs narrower, so a wider foot may prefer the men's version even if you usually buy women's shoes.

How to translate your usual size

Start with the version that matches the sizing system you normally buy. If you wear a women's 8, order the Women's Pacific in your usual women's size. If you wear a men's 10, order the men's Pacific in your usual men's size. Do not simply subtract or add a fixed number between men's and women's sizes, because the last shape differs, not just the length.

For a unisex waterproof sneaker fit, the closest match is usually the version that matches your foot's width and volume. A narrow foot in a men's version may feel sloppy; a wide foot in the women's version may feel tight across the instep. If you have worn Vessi before, use the same gender version and size you already know works.

Sock choice changes the fit more than you think

Sock thickness is the easiest variable to control. A no-show sock like the No Show Socks - Fusion/Midnight keeps the fit close to your bare-foot size, which is useful if you are between sizes or want a snug feel. A thicker crew sock adds volume and can make a slightly loose pair feel secure.

If you plan to wear the Pacific for running errands or travel, most people pair it with a low-profile sock. If you plan to wear it in colder weather with thicker socks, consider sizing up half a size only if the catalog offers it; otherwise choose the version with more volume for your foot.

Trade-offs to weigh before you choose

Women's Pacific fit: Built on a women's-specific last, so it is narrower and lower-volume than the men's version. Choose this if you normally wear women's sizes and have a narrow to average foot.
Men's Pacific fit: Built on a men's-specific last, so it is wider and higher-volume than the women's version. Choose this if you normally wear men's sizes or have a wider foot.
Sizing system: The two versions use different size scales, so your usual women's size and usual men's size are not directly interchangeable. Order the version that matches the sizing system you already know.
