Lightweight casual slip-ons

About Hey Dude: Hey Dude is an Italian casual footwear brand, founded in 2008 and now part of the Crocs group. The Wally and Wendy slip-ons made the name: very light, flexible soles, stretch laces and a soft insole that feels comfortable straight from the box. We stock them for relaxed everyday wear, holidays and anyone who finds conventional trainers a bit heavy on the foot.

Hey Dude fit & sizing tips

  • Whole sizes only. Hey Dude adult shoes come in full sizes, not halves. If you are between sizes, the brand suggests sizing down for a snugger fit or up for more room; fit varies a little between styles, so check the product notes if you can.
  • True to size, but check the style. Most Hey Dudes fit as expected, though some canvas and knit uppers feel a touch generous. Narrow feet may want to go down; wider feet often find their usual size fine.
  • The sole flexes with your foot. The light, flexible sole needs almost no breaking in and feels slipper-soft from the first wear.
  • Stretch laces and forgiving uppers. Many styles use elastic laces or stretch fabric rather than a stiff traditional upper, which makes them easy to slip on and more forgiving through the forefoot.
  • Our take. A great everyday casual shoe, especially for anyone who finds trainers too heavy or stiff.

Hey Dude Women’s Shoes

Hey Dude women’s shoes are marked in US sizes on the box, which run two sizes above UK, so a UK 5 is a women’s US 7. They are made in whole sizes and come up true to size; if you are between sizes, the stretchy uppers usually make the smaller size the better choice. We stock from UK 4 (EU 37) to UK 8 (EU 42).

Glossary

Flex and fold sole

Hey Dude’s signature ultra-light, flexible outsole that bends with the natural movement of the foot.

Memory foam insole

A soft, moulded insole in most Hey Dude styles. It is removable on many pairs, which also makes washing the uppers easier.

Stretch lace

An elasticated lace system used on many styles that gives a snug, slip-on fit without needing to be tied.

Frequently Asked Questions

Do Hey Dude shoes run true to size?

In our experience, most styles fit as expected, but Hey Dude themselves say some models run slightly small or large. The stretch uppers on Wally and Wendy styles give a relaxed feel, so narrow feet may want to size down and wider feet often find their usual size is fine.

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

Hey Dude adult shoes are sold in whole sizes only. Their own guidance is to size down for a tighter fit or up for a looser one. We would usually size down if you are between halves and prefer a snug slip-on, and up if you want more toe room or wear thicker socks.

Are Hey Dudes good for wide feet?

They suit wider feet better than many casual shoes. The knit and canvas uppers have give, and selected Wally and Wendy styles are available in a wide fit. They are not a formal wide fitting across every model, but the standard shapes are roomier than a typical trainer.

Do Hey Dudes need breaking in?

Hardly at all. The flexible sole and soft insole feel comfortable from new. If anything feels tight, it is usually length rather than something that will ease with wear, so use the foot length in cm on our chart rather than hoping they will stretch.

Why does my box show a US size?

Hey Dude labels shoes in US sizing on the box and footbed, even when you order by UK size on our site. Match your foot length in cm and the EU size in our chart rather than worrying about the US number on its own.

Can I machine wash my Hey Dudes?

Canvas and knit styles can go in the washing machine on a cold, gentle cycle if you remove the laces and insoles first, then air-dry out of direct heat. Suede, leather and wool pairs should be spot-cleaned only; machine washing can void the warranty.
