1 - 15 . (canceled) 
     
     
         16 . A shoe, in particular sport shoe, having a sole and a shoe upper part connected to the sole,
 wherein the sole is made, at least in sections, from an expanded thermoplastic polyolefin, wherein the section of the sole consisting of expanded thermoplastic polyolefin consists of a plurality of spherical or ellipsoidal plastic bodies which are joined to one another in a substance-locking manner, and wherein the dimensions of the single plastic bodies in the three spatial directions are between 0.5 mm and 5.0 mm,   wherein the section consisting of expanded thermoplastic polyolefin forms an insert of the sole, wherein further sections of the sole consisting of a material which is not expanded thermoplastic polyolefin,   wherein the further section of the sole, which does not consist of expanded thermoplastic polyolefin, consists at least in sections of an ethylene-vinyl acetate copolymer, of expanded thermoplastic polyurethane, of thermoplastic polyurethane, of thermoplastic elastomer, of polyamide, of foamed polyurethane and/or of rubber material.   
     
     
         17 . The shoe according to  claim 16 , wherein the substance-locking bond of the plastic bodies has been made by a welding process. 
     
     
         18 . The shoe according to  claim 17 , wherein the welding process has been carried out by introducing steam into a mold under a pressure of between 1.0 and 4.0 bar, preferably between 1.0 and 2.0 bar. 
     
     
         19 . The shoe according to  claim 16 , wherein the substance-locking bond of the plastic bodies has been made by an adhesive process with the addition of an adhesive. 
     
     
         20 . The shoe according to  claim 16 , wherein the plastic bodies have a weight between 5 mg and 10 mg. 
     
     
         21 . The shoe according to  claim 16 , wherein the section of the sole consisting of expanded thermoplastic polyolefin has a density between 100 and 250 g/l. 
     
     
         22 . The shoe according to  claim 16 , wherein the plastic bodies consisting of expanded thermoplastic polyolefin have a density of between 70 and 140 g/l before they are joined together. 
     
     
         23 . The shoe according to  claim 16 , wherein the section consisting of expanded thermoplastic polyolefin forms a midsole of the shoe. 
     
     
         24 . The shoe according to  claim 23 , wherein an outer sole is arranged below the midsole. 
     
     
         25 . The shoe according to  claim 16 , wherein the section consisting of expanded thermoplastic polyolefin does not extend over the entire height of the sole or midsole. 
     
     
         26 . The shoe according to  claim 16 , wherein the section consisting of expanded thermoplastic polyolefin is arranged in the heel region of the sole.
