In-shoe stability

Polyurethane Grip

A high-performance synthetic polymer engineered for durable, high-friction grip. It locks your foot to your shoe through micro-surface friction — and unlike adhesives, it keeps working even when wet — preventing the internal slippage that causes blisters and black toenails.

APP Tour pro Ryler DeHeart puts RTP UltraGrip Socks to the test on court.

🧦In-Shoe Stability

Grip the court. Grip the racket. Never slip again.

Stop sliding. Prevent injuries

Dual-sided grip locks your foot to your shoe — even wet — so it can't slip and cause blisters or black toenails.

2-Sided Grip zones inside AND outside the sock
Wet or Dry Grip stays locked to your shoe — most socks lose grip when wet

Dual-sided non-slip pads

Grip pads on both inner and outer surfaces lock your foot to the sock and the sock to the insole. No movement, either way.

2

Moisture wicking instep mesh

Mesh panels at the instep keep conditions dry as intensity builds. Consistent grip, from first whistle to last.

3

Integrated arch band & cushioning

Reinforced arch band keeps grip pads aligned through every cut, with full-sole cushioning for added protection.

4

Targeted toe grip zones

Reinforced toe grip pads prevent forward foot slide during explosive acceleration and sudden stops.

What is Polyurethane?

材料

What is Polyurethane?

🧬

分子工程化

可精确调节软硬、柔韧或支撑性——聚氨酯的性能可在分子水平上进行控制,不同于普通泡沫材料。

🛡️

吸收冲击,抗变形

在反复受压时仍能保持结构,而不会随着时间的推移而产生永久压缩变形。

⚖️

平衡缓震与控制

其他材料难以兼具的特性——足够柔软,可提供缓冲;足够强韧,可提供支撑。

👟

专为保持鞋履一致性而打造

无论是一次又一次的重复使用,还是次与次的训练,表现始终如一——因为一致性与舒适性同样重要。

Why Polyurethane Grip Technology Enhances Stability & Performance

为什么有效

Why Polyurethane Grip Technology Enhances Stability & Performance

🔩

经久耐用、富有韧性

能够承受反复摩擦和压力,因此握把不会像较软的材料那样快速磨损。

🦶

将足部固定到位

高摩擦力的鞋面可防止脚在鞋内产生多余移动——减少能量损耗,降低起水泡的几率。

🤸

灵活,绝不妥协

自然贴合足部动作,同时保持强力抓地性能。

🌡️

在任何条件下都保持一致

轻巧且耐湿、耐温差,因此性能不会下降。

The Three Mechanisms of Polyurethane Grip

抓地表现

The Three Mechanisms of Polyurethane Grip

🔬

微表面摩擦

微观不规则纹理可与鞋垫相互咬合——即使在光滑的 EVA 泡沫或皮革上也能提供抓地力。

↩️

弹性回弹

蹬地时压缩,随后立即回弹——始终“吸附”在鞋垫上,而不会滑动。

💧

抓地力始终稳固,无论干湿路面

机械摩擦力,而非粘性——因此即使汗水增多,抓地力依然稳固。
