Mono-fin with flexible boot structures

Abstract

A mono-fin for swim training is disclosed. The mono-fin has two separated boot structures that from two separate foot cavities for holding feet with toes positioned in front regions of each of the boot structures and heels positioned at back regions of each of the boot structures. The mono-fin has a mono-fin structure connecting the boot structure through the front regions of each of the boot structures. In a middle region of the mono-fin structure and between the front regions of the boot structures, there is flex region. The flex region allows angles between the boot structures and distances between the back regions of the boot structures to be changed by a swimmer while swim training.

What is claimed is: 
     
         1 . A mono-fin comprising boot structures with separate cavities for holding feet each attached to a mono-fin structure near toe regions of the boot structure, wherein the mono-fin structure is flexible, such that angles between the boot structures and distances between the boot structures are changeable while swim training. 
     
     
         2 . The mono-fin of  claim 1 , wherein the boot structures and mono-fin structure are monolithic. 
     
     
         3 . The mono-fin of  claim 1 , further comprising strap features for securing the feet within the separate cavities. 
     
     
         4 . The mono-fin of  claim 1 , where in mono-fin structure has protrusion features positioned in front of toe regions of each of the boot structures and a valley or V-shaped indentation positioned between the protrusion features. 
     
     
         5 . A mono-fin comprising:
 a) boot structures with separate cavities for holding feet with toes positioned in front regions of each of the boot structures and heels positioned at back regions of each of the boot structures; and   b) a mono-fin structure coupled to the front regions of each of the boot structures, with a flex region, such that angles between the boot structures and distances between back regions of the boot structures are changeable while swim training.   
     
     
         6 . The mono-fin of  claim 5 , wherein the boot structures and mon-fin structure are monolithic. 
     
     
         7 . The mono-fin of  claim 5 , further comprising strap features for securing the feet within the separate cavities. 
     
     
         8 . The mono-fin of  claim 5 , where in mono-fin structure has protrusion features positioned in front the front regions of the boot structures and a valley or V-shaped indentation positioned in front of the flex region of the mono-fin structure. 
     
     
         9 . A mono-fin comprising:
 a) two separated boot structures for holding feet with toes positioned in front regions of each of the boot structures and heels positioned at back regions of each of the boot structures; and   b) a mono-fin structure coupled to the front regions of each of the boot structures, wherein the mono-fin structure has a flex region positioned in a middle region of the mono-fin structure and between the front regions of each of the boot structures such that angles between the boot structures and distances between the back regions of the boot structures are changeable while swim training.   
     
     
         10 . The mono-fin of  claim 9 , wherein the boot structures and mon-fin structure are monolithic. 
     
     
         11 . The mono-fin of  claim 9 , further comprising strap features for securing the feet within the boot structures. 
     
     
         12 . The mono-fin of  claim 9 , where in mono-fin structure has protrusion features positioned in front of the front regions of each of the boot structures and a valley or V-shaped indentation positioned in from of the flex region of the mono-fin structure.
