The benefits of soft isolation have long been established and applications for the soft shoe are inlimited. They are soft enough for effective isolation of lightweight components such as CD players but strudy enough - especially if doubled up in back-to-back pairs - to support heavy power amplifiers. Small enough for speaker/stand isolation but adaptable enough to be used for example in conjunction with Tenderfeet if desired. The Soft Shoes are supplied in packs of 12 at £18.00 per pack - just £1.50 each. Which makes it well worth experimenting!
