Have wide feet? We recommend going half a size up for a more comfortable fit.

Not sure what the right shoe size is for you?

The following instructions will help you choose.

  • Take a piece of paper and a pen or pencil
  • Stand with your heels against the wall
  • Stand upright, placing your weight on both feet
  • Get someone else to draw a line at the tip of your toe
  • Measure the length from the wall to the line
  • Add 3-5 mm to the measured length (important for toe space)
  • Compare the foot length with the size chart

Finally, a sandal that moves with your foot instead of fighting it.

Ultra Flex Knit Sandals combine a stretchy knit upper, a cushioned platform sole, and an elastic ankle strap — the sporty-chic sandal that gives you the support of a trainer with the breathability of a sandal, all day long.

✅ Stretchy knit crossover straps — adapt to any foot shape, wide or narrow, zero pressure ✅ Elastic ankle strap — slip on and off in seconds, secure fit all day ✅ Cushioned platform sole for orthopedic-level shock absorption ✅ Lightweight and breathable — keeps feet cool even on the hottest days ✅ Machine washable — fresh and clean after every wear, no effort needed

The dress looked just like the photos and feels lovely to wear. Feminine, comfortable and easy to style.

Very pleased with the blouse. The fabric feels soft, the fit is flattering and the colour is beautiful.

The sandals are lightweight and comfortable. They look elegant and were easy to wear throughout the day.

These trousers are comfortable without looking too casual. I can easily wear them during the day or for dinner.

Great service! Easy exchange after the heels turned out too small.

The ordering process was simple and I was kept informed about my order. Everything arrived neatly packaged.

I appreciate that the styles feel modern without being too trendy. The top is flattering and very comfortable.

This Is Goodbye. But First, Thank You.

I started Montrose Boutique with one simple dream: to help women feel confident in clothing they truly love.

Over the years, our small boutique became so much more than a shop. It became a community, and a chapter of my life I will always cherish.

Unfortunately, rising costs and the growing pressure of running an independent boutique have made it impossible to continue.

After many sleepless nights, I have made the heartbreaking decision to close Montrose Boutique.

We are now holding our final clearance sale, with up to 80% off our remaining collection.

Limited stock is available. Once it is gone, it will not be restocked.

Thank you for being part of this journey.

With love and gratitude,

Claire Morrison

Founder of Montrose Boutique
