Shoe Stretcher Guide
The steps below show how to use your Premium Shoe Stretcher for a precise, comfortable fit.
Thank you for your recent purchase. If your shoes are tight or causing discomfort, your Premium Shoe Stretcher is designed to relieve pressure and improve fit. Follow this guide for the best result.
Before You Begin
Before inserting the stretcher into your shoe, take a moment to reset it to its starting position. This means ensuring both the widening handle and the lengthening wheel are fully closed. Beginning from this position allows the stretcher to slide easily into the shoe and prevents the mechanism from binding or getting stuck during insertion.
Step 1. Prepare the leather
Apply Trimly Shoe Stretch Spray inside the tight area of the shoe. This helps relax the leather so it can stretch safely.
Insert [E] spot stretching bunion plugs into the toe block, if required.
Step 2. Insert the stretcher
Slide the toe block (A) into the toe box of the shoe.
Ensure the heel block (B) sits fully inside the shoe before adjusting the stretcher.
Step 3. Adjust the length
Turn the lengthening wheel (C) counter-clockwise to move the heel block towards the back of the shoe.
Once the stretcher feels snug, turn the wheel two to three additional turns to apply stretching pressure.
Step 4. Adjust the width
Turn the widening handle (D) clockwise to expand the toe block and widen the shoe.
Once resistance is felt, add two to three additional turns to create the stretch.
Step 5. Leave stretcher in place
Leave the stretcher inside the shoe for 6–8 hours.
For tighter shoes or thicker leather, leaving it overnight often produces better results.
Step 6. Remove the stretcher
To remove the stretcher, first release the pressure:
- Turn the lengthening wheel (C) clockwise
- Turn the widening handle (D) counter-clockwise
This retracts the blocks so the stretcher can be removed easily. Pull it out slowly.
"When you start to feel tension, give the turning handle three more turns. That's the sweet spot."
FAQ Stretching Your Shoes

Applying too much tension can overstretch your shoes, leaving them loose and misshapen. It can also damage the stretcher’s threading, making it difficult or impossible to use.
