Rick has one less than three stripes, or 3-1=2 stripes on each tennis shoe.
Hortense has double the 3 stripes that Olga has, or a total of 3*2=<<3*2=6>>6 stripes per shoe.
Since each of them has two tennis shoes per pair, then the total number of stripes on all of their shoes is 2*(3+2+6)=<<2*(3+2+6)=22>>22 stripes
