+1 for this!!You can pick up a good cheap pair of military style boots online... might be more beneficial and tick all the right boxes....
You cant get better than a pair of steel toed military boots. Great grip tread, ankle support, toe protetion and if you polish the leather every now and again 99% water proof. You don't even have to spend a fortune. Brand new Gortex or Berghaus boots can set you back upwards of £120.
My last 3 pairs have come part worn from an army surplus store for under £30. Bang a new pair of insoles in them if you want and you're good to go!
Google army surplus stores in your area, theyre everywhere and always have a reasonable selection of sizes.
