All of our products have meet CE EN345 standard and can be further divided into the following categories:
SB: Shoes comply with basic requirements only
S1: Antistatic properties, outsole resistant to oils and fuels, energy absorbed in heels
S1P: Same as S1+ steel midsole
S2: Same as S1+water penetration and absorption
S3: Same as S2+puncture-proof and tread pattern
And the main methods are PU/PU injection, EVA+Rubber cemented, TPU/PU injection and PU Rubber injection.

Also we have our own QC team and before every shipment, they must have three inspections for each order:
1) examine the material Before production;
2) two QC check together before the injection outsole;
3) 100% confirmation before the package. We effect the shipment only after the inspection result is OK. As you know, the QC has to write down all the information on an Inspection Report and then pass this Report to every sales person for last confirmation!
      Now we have 2 designers and 6 sample-makers. So we guarantee all the new samples will be finished and send for customer's confirmation in 10 days after we receive your sample photo. 
      You can log on our website that it's www.topsafetywear.com and know more information.
Sincerely wish we would have a nice cooperation in near future!
