Width fittings explained

We have several options available, though many of our styles have different fits. You can filter by width of the fit from our search page. The fittings are:

M - Accommodate feet that require slightly less space than our W fitting styles.

W - Our standard fit which should suit most people. If your big toe joint/small toes begin to feel pinched or ache, then you may want to try our roomier XW fit.

FF - Based off our W fit. You can tailor the fit to allow for more or less room in the shoe by swapping or removing the forefoot inserts which are included with the shoe.

XW - Allows for a little more room over the instep or at the front part of the sandals, shoes or boots than our W fitting styles.

XF - Based off our XW fit. You can tailor the fit to allow for more or less room in the shoe by swapping or removing the forefoot inserts which are included with the shoe.

XXW - Looks after a foot which needs more space over the in step or the fore foot area. If our XW is a little tight the XXW could be just right.

Fitting advice

If you would normally take a half size, e.g. 37.5, but the style you're looking at doesn't come in halves, we recommend you select a larger size.

If you find shoes are often a bit tight in width, or shoes which are one size larger than your true size feel more comfortable across your feet, we recommend that you select the W width.

If you find it very difficult to find shoes that are comfortable in width or usually seek out shoes that are made for extra wide feet, then an extra wide fitting is most suitable. Opt for the XXW width.

If you experience gaping material around the mid-section of your foot, and the tendency for your foot to slip side to side in the shoe, a narrow fit is most suitable. Opt for the M width.

Some styles have adjustable features, such as adjustable straps. This information is detailed on the product pages.

If you would prefer to be fitted in person before you purchase, we suggest you visit a Ziera specialist store where we can help you find your perfect fit.

Three generations of shoes

Fashions may have changed over the past 70 plus years that we've been in the shoe business, but our conviction that women deserve the best of both style and comfort is unchanged. This belief has seen Ziera evolve from our foundation in New Zealand to bring beautiful comfort to women around the world.


Brothers-in-law Mervyn Adams and David Robertson went into partnership as podiatrists. Looking for footwear to recommend to their clients, they found a lack of styles they believed to be orthopedically good enough. They set out on an ambitious project to study 10,000 women's feet and create unique 'lasts' (shoe moulds) based on the anatomical need of the women.

Mervyn Adams


A local manufacturer was found.
The range they developed - known as Mervyn Adams Arch Supporting Shoes - was instantly successful.


The first Mervyn Adams store opened in
Hamilton, New Zealand.

The company moved into manufacturing with its own factory.


Exports began to Australia, and towards the end of the decade, into the American market.


A time of tremendous growth, the factory relocated twice in the early 1980s. More space was needed to expand and meet demand. John Robertson, the son of founder David Robertson, took over as Managing Director in 1980.

The first of Ziera store opened in Australia, in Sydney's Parramatta Shopping Centre. The shoes began to be marketed under the Kumfs name in 1996.


The first US Kumfs store opened in Fresno, California.


All manufacturing was shifted to a factory in Guangdong, China.

China production facility


Ziera, a fresh brand name, was launched but the focus on stylishly comfortable shoes remained the same.


A new Auckland super store opened on Broadway, Newmarket. The store fit out was updated along with the new logo and livery.


Now, just like back in the 1940s, a dedication to both style and comfort is something that's at the heart of the Ziera business.

This family-owned New Zealand company is now headed by the third generation of Robertsons - Andrew, grandson of the founder.
