Q: Should I wear socks with Riomar shoes?

Riomar shoes are built to fit snug and to be worn without socks. The lining is odor-proof and antimicrobial, so going sockless is the intended experience, and it is how you should judge the fit when you first try them on.

Q: What sizes do Riomar shoes come in?

Men's styles are offered in half sizes from US 8 through 12, then in whole sizes 13, 14 and 15. Women's styles are offered in half sizes from US 5.5 through 10.

Size & Fit

Riomar shoes are made by hand in Portugal on a European last, and they run true to size. Find your US size below for the EU equivalent, then read the fit notes – particularly the one about width.

We build one width: standard American medium. We do not offer narrow or wide fittings in any style.

Because our last is European, our shoes are best worn snug, without socks.

How Our Shoes Fit

Do Riomar shoes run true to size?

Yes. Order the US size you normally wear. Our shoes are built on European standards and can run slightly narrower than a standard American shoe, but the length is true.

Do you offer wide or narrow widths?

No. Every Riomar style is built in one width, standard American medium. If you typically need a wide fitting, reach out to the Commodore at customerservice@riomarshoes.com before you order and we’ll give you an honest answer about whether they’ll work for you.

Should I wear socks with them?

Our shoes are built to fit snug and to be worn without socks. The lining is odor-proof and antimicrobial, so going sockless is the intended experience – and it’s how you should judge the fit when you first try them on.

Will my shoes stretch?

A little, where your foot wants it – but how much depends on the leather. The suedes are the supplest and will give the most. The Fathom series is the most firm and will give the least. Everything else sits in between.

I’m between sizes. Should I go up or down?

Write to the Commodore at customerservice@riomarshoes.com and tell us the style you’re looking at and what you normally wear. Because the leather and last differ between our lines, the right answer changes by style – we’d rather advise you than guess.

Does the waterproofing change the fit over time?

No. Our leathers are fully waterproofed during the tanning process rather than treated on the surface, so getting them wet won’t shrink them or change how they sit on your foot. They are built to perform on the water – though, to be clear, this is no water sock.

Still not sure? Reach the Commodore at customerservice@riomarshoes.com for personalized advice – tell us the style and your usual size and we’ll help you land it.

Description

The Riomar Waterman is a men's waterproof leather boat shoe, defined by its versatility. Its hybrid driver sole, low profile lines, and technical capabilities are designed for optimum performance on and off the water, which makes it the ideal shoe for everyday wear.

Every pair is handcrafted in Portugal from waterproof European leather, with precision hand stitching, a non-skid, non-marking sole, and an odor-proof, antimicrobial lining.

The Waterman also carries our patented Bearings, swappable accents hand tied in the USA by our Bearing Masters, so a single pair may change its colors as often as its owner pleases. Change Your Bearings, Not Your Sole.

Change your bearings, not your sole

Our bearings are hand tied by fishermen in Florida. Each one shackles across the vamp and comes off in seconds with no tools, so a single pair of shoes carries more than 130 different looks. If you would rather fly your own colors, our Bearing Masters will tie those too.
