Do UGGs fit true to size?

UGGs generally fit true to size. However, you want your new UGGs to be fitting as a glove. when time passes by, the wool liner will begin to flatten making them a little roomier. New UGGs need to be tight to the foot.

How to Measure your Uggs Shoes Size

How do I know my size in UGGs?

The best way to check your UGG size is to measure your feet!  A full understanding on how to measure your feet you can read here

  1. Stand on a piece of paper straight against a wall.
  2. Get someone to mark the top of your top and the back of your heel. you can do this by yourself as well
  3. Measure the distance between these two points.

Time needed: 3 minutes.

How do Uggs fit and how to define the perfect fitting UGG Size?
10 easy steps to measure your feet correctly:

  1. Measure your feet in the afternoon.

    Your feet tend to swell in the afternoon, so it’s best to take dimensions by the end of the day.

  2. Stand When Measuring

    When in a wheelchair there’s no pressure on the feet, so it’s unnecessary to stand up.

  3. Wear socks

    Uggs are worn with and without socks. Based on your choice wear them (or not) when measuring your foot. Generally, you shouldn’t wear socks in uggs.

  4. Be precise

  5. Measure both feet

    Measure your left and right foot separately as they’re not the same length. Take the biggest measurement to determine your Ugg Size

  6. Stand on your piece of paper

    For Wheelchair users, you can go immediately to step 8 and measure the length of the feet with measuring tape.

  7. Start drawing

  8. Measure the length of your feet

  9. Find your width fitting by drawing or with measuring tape

    Uggs only come in 1 roomy width, so no need to take your width measurements

  10. Determine your Ugg size in the conversion charts

Will UGG boots stretch?

The sheepskin exterior won’t stretch, the inner lining will become compressed like your boots have stretched or become roomier. Buy your new UGGs really true to size, but not too tight. A perfect-fitting UGG must hold your foot like a glove. 

Consider buying wool insoles, when your UGGs are well worn and the lining has lost its initial volume.

Do you go up or down a size in UGGs?

When you’re in between sizes with your UGG size measurement, it’s best to go 1 size down. The reason is already explained on this page: The lining will become less dense and this will cause a more roomy fitting.
