Product Insights
Fleece-Lined Mule Slippers Men 139 CAD Product-specific guidance says these run true to standard US sizing. Backless mules stay on through friction across the ball and instep, not a heel counter. Rubber outsole is chosen for abrasion resistance and traction, good for indoor and short dry outdoor use. Two colorways: Black and Light Brown.
Verified claims
- design
- Backless mule slipper with closed rounded toe and open low heel.
- materials

- fit
- Backless mules stay on through friction across the ball and instep, not a heel counter.
- use
- Not built for running, climbing loose ground, or fast movement.
- fit
- A good backless fit grips the ball, leaves a 1/4–1/2 inch toe gap, and allows under 1/4 inch heel lift.
- fit
- If they slip, try ball-of-foot cushions, heel grips, insoles, no-show socks or footbed spray before resizing.
- comfort
- Keeping a backless mule on can require active toe gripping, which may cause fatigue, calluses and gait changes over time.
- design
- Vamp coverage is a main security feature on a backless mule.
- construction
- Textured rubber outsole helps hold the foot from below, reducing internal forward slide.
- materials
- Breathable lining reduces moisture that makes feet slide inside a slip-on.
