Im not quite sure how size of a shoes can bend a support rod? But hey ho. Bent support rods are weaker support rods. In that whilst they still do the job pefectly well, they will break 'sooner'. ive bent some in the past , missing a jump and the footplate landing where the hoof should have. I left it and when it broke I finished the last few hundred metres of last years 'Walk for Life' with 1 VVV wobbly bock. With next day delivery ( assuming stock in stock- tho remember this part is inter changable between brands), when the part breaks its not really going to be a big issue ( OK 1 days bocking shortened 2 if its at a weekend).
But break a bent support rod will, so u might just want to buy a pair ( they go 1 at a time so you can stagger the purchace) to be ready.
