Hi all , just to warn you all , be aware of karrimor hot rocks " extreme waterproof " boots .cos they are NOT !! Bought a pair just a couple of months ago and they leak like a sieve . contacted the supplier "kickback sports" which is "sports direct" online , who indicated they are only waterproof at time of purchase and not once you put them on "" staggering . They told me they need regular reproofing , bit strange as they are sold as having a waterproof membrane - dont know how you change that . And of course you can only return them within 14 days if you havnt worn them !! . I should have known better but only wanted them as a lightweight dog walking boot . Remember Karrimor is owned by "sports direct" with their legendary customer service .didnt know that when purchased , so be warned .Any one else purchased a Karrimor product and been disappointed by the new quality standard ?? . Happy walking and keep your feet dry
