TYR Hydroblade Swim Training Fins Medium Yellow - Quick Flutter Kick

Our review of the TYR Hydroblade Swim Training Fins finds them best for swimmers seeking a comfortable, responsive fin that promotes short, quick flutter kicks in lap and drill work. The Medium size (Mens Shoe 6-7, Womens 7.5-8.5) fits a narrow size range, and the single biggest reason to buy is the silicone construction and channelled blade design that combine to improve kick mechanics without feeling restrictive. The fins are notably comfortable thanks to a soft heel strap, pull tab and rounded foot cavity edges, which means longer sessions are easier on the feet.

Key Features

• 100% Silicone Construction: Provides a flexible, durable fit that reduces chafing and keeps the foot comfortable during extended sets.
• Engineered Blade Shape: The angled blade surface and channel side rails amplify power and create upward resistance to reinforce a natural flutter kick.
• Comfort Fit Heel: An innovative heel strap and convenient pull tab make the fins easy to put on and remove while maintaining a secure fit in the water.
• Rounded Foot Cavity Edges: Rounded edges prevent pressure points so swimmers are less likely to feel discomfort inside the fin.
• Medium Sizing: Sized for Mens Shoe 6-7 and Womens 7.5-8.5, targeting swimmers who need a snug, performance-oriented fit.

Who It's For

The Hydroblade Medium fins are aimed at recreational and competitive swimmers who want to improve kick technique and ankle flexibility with short, rapid strokes; they work well for lap training, drill sets and technique-focused sessions. Coaches and masters swimmers who use fins to accentuate flutter kick mechanics will find the silicone build and channel rails give useful feedback on stroke timing.

Swimmers needing a roomier or larger fit should look elsewhere since the Medium sizing runs true to narrow and some users report a tight fit. Those seeking an extremely soft, full-foot snorkel-style fin with minimal resistance may also prefer a different, longer-blade model.

Pros & Cons

Pros

• Comfortable silicone construction and rounded edges reduce foot irritation during long sets.
• Channel side rails and angled blade surface increase propulsion and teach a natural flutter kick.
• Secure heel strap and pull tab make them easy to don and remove while staying in place during hard kicking.

Cons

• Medium size fits a limited range and may feel tight for some users, so careful size selection is required.
• Some swimmers expect a stronger thrust from the short blade and may find them less powerful than larger training fins.
