For Maver Pole Rollers;
Common issue of the feet breaking on these, here are some replacements.
Simply remove your old ones, and fit these in place, a bit of glue is advised to keep them in place (any universal glue will work) silicone based is advised rather than superglue due to the slight flex of the legs. 
These come in packs of 2, I will happily supply with a 6 month warranty; for any clear issues of breakages, replacement can be organised with only the price of postage.
