The present invention relates to a shock absorber (10,20) for use in a shoe (40).
The shock absorber (10,20) comprises an elastic body (25,25) arranged with a plurality of tubular cavities (24) axially extending into the elastic body (25,25) from its under side and ending in the body.
Thus, by providing the shock absorber (10,20) according to embodiments of the present invention, it is possible to advantageously adapt to the moulding material forming the midsole of the shoe (40) in which the shock absorber (10,20) is arranged in that when injecting the material in the casting mould onto which the upper, insole (30) and shock absorber (10,20) is placed, the moulding material (typically being polyurethane) will push up into the tubular cavities (24) and thus into the shock absorber (10,20). Hence, the moulding material hardening under the shock absorber (10,20) in prior art manufacturing process will now enter the tubular cavities (24) and thus avoid pushing the shock absorber (10,20) upwards into the shoe.
