I have used various ankle and wrist weights over the past for my regular walks (1+hr).
So far these seem excellent, comfortable and have been used as ankle weights and haven't yet split. Iuse the sand-filled power gloves as well.
Other ankle weights which were similar price or cheaper may have been as comforatble but one pair of ankle weights split open on the 3rd use = rather unpleasent having to remove loads of sand from my trainers and socks when I was in the middle of nowhere and it was raining :-)
Based on the use so far I'd recommend these and will defiantely consider buy more.
