Land End Water Shoes

It will be appreciated that the curve 6 approximates the motion shown in FIG. This configuration reduces drag in the forward direction while providing desired drag in the aft direction.
(McMinnville, OR, US) Thomas, Jeffrey A. This applies the drag forces to the side of the user's foot near the bottom of the shoe to simulate the forces applied by contact with the ground in land-based running. The use of the largest scoop at the rear of the shoe is advantageous because the rear part of the shoe is better able to accommodate a large scoop and also because that places the most drag at the runner's heel, which further assists in simulating pc to landline call the feel of land-based running.
This places the drag forces lower on the shoe to further assist in simulating the application of forces that arise during land running. Increased overall benefit to the runner and an improved “feel” of the DWR exercise are achieved.
Scoop 14 is preferably placed at the rear of the shoe and may be placed at the heel so that the rearmost part of the scoop 14 is flush with the rear of the shoe.

Several sources describe “proper” DWR techniques, but it appears that the most common DWR style is characterized by a high-knee or piston-like leg action.

4 b is a side view of the scoops shown in FIG. Apparatus according to claim 9 wherein the depth of said scoop is from about 6 mm to about 40 mm, the height of said scoop is from about 19 mm to about 75 mm, and the length of said scoop is from about 12 to about 50 mm. In the preferred embodiment, a shoe has 2 to 4 scoops arranged longitudinally on each side of a shoe, and preferably has three such scoops on each side.
In addition, instability of the shoe results in transmission of forces to the runner, which could affect the runner's hip, knee, and ankle joints. Apparatus for use in exercising in water comprising a shoe adapted to be attached to the foot of a user, said shoe comprising a plurality of drag-generating elements attached to each side of said shoe for generating drag forces on said shoe during use, wherein said drag-generating elements generate more drag for movement of said shoe in a rearward direction than in a forward direction. Because the foot does not move strictly linearly (see FIG. Attached to the foundation along each side of the shoe are scoop-shaped protrusions.
4 a , 4 b , and 4 c illustrate preferred configurations and arrangements of the scoops. An advantage of a scoop is that it is conveniently attached to the shoe by stitching and may be conformed to the shape of other structures on the shoe whereby the same stitching is used for the scoop as well as for the other structures. The center scoop, located near the arch, is somewhat smaller.

Apparatus according to claim 1 wherein each of said drag-generating elements comprises a scoop having an open end and a tapered front surface.

1 illustrates the motion of the ankle of a runner when running on a treadmill. Thus, the majority of the drag is provided by the rearmost scoop, and the drag provided by the foremost scoop is the least. Accordingly, the height of the scoop in the forward part of the shoe is often limited. Read item description for any reference to return policy. Scoop 14 would be placed at the rear of the shoe and is the largest of the three scoops. - Previous Patent (Force assistance dev. In contrast, the cross-country style is intended to be more like land-based running.

It will be appreciated that while the preferred embodiment utilizes scoops to provide the desired degree of increased drag as described above, other elements may be provided with similar effect. Configuring the scoops with tapered front surfaces also allows the water to flow around the rear scoop and engage the scoop in front of it with less turbulence.
One objective in placing the scoops in a symmetrical fashion is to ensure that the forces arising from fluid drag on both sides of the shoe are approximately equal. Optimally the drag when moving in the backwards direction is 25%-30% greater than when moving in the forward direction. The spacing of the scoops may be in the range of from about 50 mm to about 75 mm and preferably about 57 mm. Apparatus according to claim 10 wherein the depth of said scoop is from about 9 mm to about 22 mm, the height of said scoop is from about 25 mm to about 63 mm, and the length of said scoop is from about 18 mm to about 45 mm.

The shoe includes a plurality of quickbooks premier non profit drag-generating elements attached to and extending from each side of said shoe for generating drag forces on the shoe during movement in water. 4 c is the depth of a scoop, “B” is the height of a scoop, and “C” is the length of a scoop and “D” is the spacing between adjacent scoops. The height of the scoops (“B”) may be in the range of from about 19 mm to about 75 mm and more preferably from about 25 mm to about 63 mm. Apparatus according to claim 5 wherein said rearmost one of said drag-generating elements is larger than the other drag-generating elements on the same side of said shoe. Apparatus according to claim 2 wherein there are three of said drag-generating elements on each side of said shoe. An object of this invention is to provide a shoe that simulates land-based running.

In the preferred embodiment, the scoops provide about 28% percent increased drag during rearward movement.

This assists in reducing flutter it is believed by reducing the effects of twisting (torsion) forces on the front of the foot by scoops that are too wide. As noted above, however, the foundation may be in the form of a sock, a sandal, a boot, or the like.
It has been reported that the DWR training method decreases spinal and joint compressive loading, which decreases the likelihood of incurring running-related injuries. It must also be remembered that the scoops create torque on the shoe, and very large scoops are therefore not generally desired for that reason. The difference in drag between a scoop and the adjacent scoop may be in the range of 10% to 20%. It will be appreciated that the bottom, somewhat linear portion, 4 of the graph represents movement of the foot when in contact with the treadmill.

Apparatus according to claim 6 comprising three drag-generating elements on each respective side of said shoe.

These protrusions are shaped to minimize hydrodynamic drag on the foot as it moves forward through the water. 2 illustrates motion of the ankle of a runner wearing a shoe according to the invention. The fins may be configured to create different amounts of drag, and applicants have found it generally advantageous for the scoop located nearest the back of the shoe to create the largest amount of drag.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is a shoe, as defined above, for use in deep water running (DWR). Great for the beach with no socks. The depth of the scoops (“A”) may be in the range of from about 6 mm to about 40 mm and more preferably in the range of from about 9 mm to about 22 mm. 99Duration:7-day listing Payment methods:PayPal (preferred)See detailsMeet the sellerSeller:big_d7( 45) Feedback:100% PositiveMember:since Sep-03-01 in United StatesSee detailed feedbackAsk seller a questionAdd to Favorite SellersView seller's other itemsContact the seller instantlyBuy safely1. 2 is a plot showing typical motion of a foot during deep water running with the article of the invention.
Despite the increasing use of DWR for rehabilitation and more recently as training to supplement a normal regimen, very little research focuses on the DWR technique. The preferred embodiment of the invention uses three scoops per side, lined up in a row from the toe of the foundation to the heel. Instability of the shoe, in turn, is transmitted to the runner and has a significant impact on its feel and its ability to simulate running on land. The shoe may have a fabric upper and an elastomeric sole and may also be provided with one or more openings or the like to allow water to drain out of the shoe after use.
The scoops create fluid drag, and the size, configuration, and placement of the scoops are important to the effective operation of the shoe in DWR. Applicants' research business home opportunity resource also suggests that wearing a shoe during DWR enhances kinesthetic perception and further helps the runner achieve a early ever november so sweet gait during DWR that is more similar box fuel tank tool to that of land-based running. This flutter is substantially eliminated by the use of more than one scoop longitudinally arranged on the side of the shoe. 4 is a top perspective view of the shoe shown in FIG.
