Shoe Sole Types: Overview of Materials and Characteristics
Complete buyer's guide: PU, TPU, TPE, EVA, PVC, rubber, and tunit — which sole is suitable for winter, city, or sports. Chosen by N-SHOES experts.
A sole is not just the bottom of a shoe. It is an engineering component that determines thermal insulation, cushioning, road grip, and shoe durability. Knowing the sole material is just as important as knowing your feet size. In this article, the N-SHOES team — a direct importer of quality footwear from Poland, Germany, and Turkey since 2009 — explains everything you need to know before making a purchase.
Why Sole Material is a Matter of Safety
With every step, the sole withstands a load several times the body weight. The material must simultaneously absorb shock, prevent slipping, retain heat, and not crack in the freezing cold.
Some polymers crystallize at temperatures below −20°C and suddenly break right while walking. Others become slippery on ice or tear at the flex point. Choosing the right material is not a matter of taste, but a matter of safety and joint health.
Three Key Selection Criteria
Season: winter requires TPE or combined TPU+PU soles; summer requires EVA or tunit.
Load: cushioning is critical for long walks; appearance is key for the office.
Thickness: for winter footwear, the minimum sole thickness is 1 cm with a deep grooved tread.
Detailed Overview of Each Sole Type
PU / PU
Polyurethane
Demiseason · Sneakers · Running Shoes
A foamed polymer with a microporous structure. Light, soft, perfectly absorbs shocks and retains heat. Ideal for spring, autumn, and everyday sneakers. Critical disadvantage: crystallizes and cracks at −20°C, slips on ice. Not suitable for harsh winters.
Lightweight
Cushioning
TPU / TPU
Thermoplastic Polyurethane
Mid-season · Business · Trekking
A monolithic dense material without pores. Maximum wear resistance, resistance to cuts. Allows reproducing an exact tread pattern. Disadvantages: heavy, poorly retains heat, low cushioning — quickly fatigues feet on hard surfaces.
Wear Resistance
Aesthetics
TPU + PU
Combined Sole
All-season · Trekking · Premium
The best engineering answer: the bottom layer is durable TPU (grip, from −35°C to +130°C), the top layer is lightweight foamed PU (heat, cushioning). The footwear is simultaneously lightweight, warm, and wear-resistant. Minus — higher price due to two-stage molding.
Perfect Balance
Down to −35°C
TPE / TRP
Thermoplastic Elastomer
Winter · Casual
Synthetic rubber, the leader of the winter segment: remains flexible and does not crack even at −50°C. Does not slip on ice, resistant to winter chemicals. Caution: softens at +70°C — not suitable for hot summer asphalt.
Down to −50°C
Anti-slip
PVC / PVC
Polyvinyl Chloride
Kids · Slippers · Budget
A rigid thermoplastic softened with plasticizers. Very cheap, durable. Danger: at −20°C, plasticizers degrade, and the sole can crack while walking. Heavy, does not adhere well to glue.
Budget-friendly
Cracks in Frost
EVA / EVA
Ethylene-Vinyl Acetate
Summer · Beach · Sports
The lightest material in the industry. Excellent cushioning, waterproof. This is the material of sports midsoles. Weak point: pores irreversibly collapse under load, the shoe gets flattened. Absolutely not for frost — becomes slippery.
Ultra-lightweight
Cushioning
TPR / TPR
Thermoplastic Rubber
City · Mid-season
A compromise between lightweight polymers and heavy rubber. Average weight and density, high tensile strength. Evenly distributes the load, sufficient cushioning. Suitable for city wear in mild winters and mid-season.
Durability
Average Weight
Rubber / Gomma
Vulcanized Rubber
Winter · Special Footwear
A classic tested for decades. Ideal grip on any surface (wet asphalt, ice), resistance to any climate. Pairs well with a leather upper. The only downside: the heaviest of all materials.
Excellent Grip
Long Durability
Tunit / Leather-like
Tunit (Rubber + Leather)
Office · Classic · Spring-Summer
A composite made of a rubber matrix with inclusions of leather fiber. Flawlessly imitates a natural leather sole. More wear-resistant than pure leather. Limitations: very rigid, cushioning is practically absent, cold sole.

Physical Properties of Soles
| Material | Weight | Cushioning | Wear Resistance | Frost Resistance |
|---|---|---|---|---|
| PU | Lightweight | Excellent | Good | Down to −20°C |
| TPU | Heavy | Low | Excellent | Satisfactory |
| TPU + PU | Lightweight | Excellent | Excellent | Down to −35°C |
| TPE | Average | Good | High | Down to −50°C |
| PVC | Heavy | Low | High | Cracks at −20°C |
| EVA | Ultra-lightweight | Maximum | Degrades | Not for Frost |
| Rubber | Heaviest | Satisfactory | High | Excellent |
Selection by Season
Important for Winter
PVC, EVA, and pure PU are not suitable for freezing weather. At −20°C, these materials crystallize, become brittle, and can break when walking. For winter shoes, choose TPE, combined TPU+PU, or classic rubber. Minimum sole thickness is 1 cm.
| Season / Conditions | Recommendation | What to Avoid |
|---|---|---|
| Severe Winter (Frost, Ice) | TPE, TPU+PU, Rubber | PVC, EVA, PU |
| Mild Winter (City) | PU (thick), TPR | Extreme Frosts |
| Spring / Autumn | PU, TPU, Rubber | Cold Tunit Soles |
| Hot Summer | EVA, Tunit, Light PU | TPE (deforms at +70°C) |
| Sports & Outdoor | TPU+PU, EVA | Worn-out EVA Soles |
| Office & Classic | Tunit, Natural Leather | Sporty PU Soles |

Frequently Asked Questions
Which sole is the best for winter boots in Ukraine?
For harsh winters, the best choice is TPE (thermoplastic elastomer) or a combined TPU+PU sole. Both materials retain flexibility at −35...−50°C, do not slip on ice, and hold heat well. Classic vulcanized rubber is also ideal but heavier. PVC and EVA are strongly not recommended.
Why does a sole crack in winter?
The most common reason is a sole made of PU (polyurethane) or PVC. At −20°C and below, these materials crystallize: polymer chains lose mobility, the material becomes brittle and breaks during bending.
What is a combined TPU+PU sole and why is it better?
A combined sole combines two materials: the bottom layer is durable TPU (grip, wear resistance), and the top layer is lightweight foamed PU (cushioning, thermal insulation). The result is footwear that is simultaneously light, warm, durable, and slip-resistant.
How does tunit differ from a natural leather sole?
Tunit is a composite: a rubber matrix with inclusions of leather fiber. It looks identical to a leather sole but is more wear-resistant and less prone to getting wet. However, it does not provide cushioning and quickly transfers cold.
