I am a DJ on the weekend so normally I am standing on hard floors for 6+ hours without sitting. It also doesn't help that I am 6ft 4in and 275lbs either. In the past, I have spent $150 on the best shoes that I could find in an effort to relieve my sore feet but nothing seemed to work. I purchased this mat to give it a shot and boy oh boy was this the best money I have ever spent. I put my mat to the test with a 5 hour prom on Friday, 5 hour Saturday wedding, and a 5 hour Sunday wedding and my feet were NOT SORE! Also I noticed that I didnt have any lower back pain or tightness from standing in one place for a long time. Another thing I love about this mat is that is that it is very durable, wont curl on the sides and if I accidentally spill something all over it and it wont destroy it. You can also expand the footprint of this mat due to the integrated tabs to expand the area of coverage...SWEET! High 5 to New Pig for getting to my house so fast and THE PRICE WAS AWESOME! Thanks Safety-Step and New Pig to keep this happy DJ spinning the hits for years to come!
