I'm 72 and terrified of ice since I slipped two winters ago. These actually grip - I walked across my icy driveway without slipping. Easy to get on with arthritis and super warm. Wear them every day now. - Patricia M.
★★★★★
Got these for my 68-year-old mom who walks her dog every morning. She says they're the warmest shoes she's owned and the grip gives her confidence on ice. Worth every penny for my peace of mind. - Jennifer R.
★★★★★
Very warm and the grip works great on ice. Slip-on design is perfect since I can't bend down easily. Runs a little small though - I needed a half size up for thick socks. Otherwise really happy. - Carol B.
★★★★★
I'm 74 with balance issues. These keep my feet warm, water doesn't get in, and the traction is impressive. I can walk on ice without holding onto my husband anymore. Wish I'd found these years ago. - Linda S.
★★★★★
Bought for my 76-year-old mother after a close call on ice. She wears them daily and says they're the most comfortable winter shoes she's owned. My dad ordered a pair after seeing hers. - David K.
★★★★★
I'm 69 with osteoporosis so falling isn't an option. Last winter I stayed inside from fear. These changed everything - the anti-slip sole actually works and they keep my feet warm. I can visit friends again. - Susan H.
FAQ
Do these run true to size?
Yes, they run true to size with room for thicker winter socks. If you're between sizes or plan to wear heavy socks, we recommend sizing up for maximum comfort.
Are they actually waterproof or just water-resistant?
Fully waterproof. The sealed construction keeps water out completely, even in slush and wet snow.
Will the anti-slip sole work on ice?
What SIANNA's Traction System Does (And Doesn't Do)
Our advanced rubber traction pods are engineered specifically for winter conditions - they provide reliable grip on ice, snow, wet pavement, and the unpredictable mix of slush and freeze that makes winter walking treacherous.
Designed For Real Winter Conditions:
- ✓ Ice and packed snow
- ✓ Wet, slushy sidewalks
- ✓ Frozen pavement and black ice
- ✓ Indoor-outdoor transitions (no damage to floors)
- ✓ All-day wear without the shuffle-inducing weight of heavy boots
Important Traction Limitations:
While our traction system excels in winter conditions, no footwear works on every surface:
- Oily or greasy surfaces (kitchen spills, garage floors) - Oil creates a different type of slip hazard our tread pattern cannot address
- Surfaces with soap, shampoo, or cleaning products - These create slick films that exceed what traction alone can handle
- Food debris or organic materials - Act as a slip layer between shoe and floor
Critical Safety Information:
SIANNA shoes are designed to reduce slip risk in winter conditions, but traction is not the same as fall prevention. Falls can occur for many reasons beyond footwear:
- Balance issues
- Medication side effects
- Vision problems
- Environmental hazards
- Mobility limitations
If you experience any of these conditions, please:
- Consult your healthcare provider before relying on any footwear for safety
- Continue using prescribed mobility aids (walkers, canes, grab bars)
- Do not discontinue other fall prevention measures
- These are comfort shoes with enhanced traction, not medical devices
Our Promise: We provide honest traction performance for real winter conditions. We do not claim to prevent all slips or falls - anyone making that promise about footwear is being dishonest with you.
See our Terms of Service for complete safety information and return policy.
Are they difficult to put on if I have mobility issues?
No. The slip-on design means you don't need to bend down or tie laces. They slide on easily in seconds.
