Inline roller skates are provided with independent suspension systems, separately suspending one or more of a plurality of wheels. The wheels are mounted rotatably on axles, and the axles are held nominally parallel to the sole of the boot. The suspension systems include guides that maintain the axles parallel to the sole of the boot even as the wheels and axles move vertically in response to bumps and other forces.

1. A skate comprising:a first wheel having two sides; an axle associated with the first wheel and extending from one side of the first wheel to the other, the axle having two ends, one end extending from one side of first wheel and the other end extending from the other side of the first wheel; an axle support including a first portion extending along one side of the first wheel, and a second portion extending along the other side of the first wheel, each portion including an aperture configured to support an end of the axle, and where each aperture is configured to allow movement of the axle; a first receptacle proximate the first portion of the axle support and positioned outwardly from the first portion of the axle support relative to the first wheel; a second receptacle proximate the second portion of the axle support and positioned outwardly from the second portion of the axle support relative to the first wheel; a first compressible medium associated with the first receptacle; a second compressible medium associated with the second receptacle; a first compressor associated with the axle and configured to compress the first compressible medium upon movement of the axle; a second compressor associated with the axle and configured to compress the second compressible medium upon movement of the axle; a first guide system associated with and separate from the axle, where at least a portion of the first guide system is configured to contact the axle, where at least a portion of the first guide system is configured to extend into the aperture of the first portion of the axle support, where the first guide system forms a pocket that sandwiches the first portion of the axle support, spans the first portion of the axle support, and has a sliding fit with the first portion of the axle support, and where at least a portion of the first guide system is configured to contact the first wheel to hold the wheel at a substantially fixed position away from the first portion of the axle support; a second guide system associated with and separate from the axle, where at least a portion of the second guide system is configured to contact the axle, where at least a portion of the second guide system is configured to extend into the aperture of the second portion of the axle support, where the second guide system forms a pocket that sandwiches the second portion of the axle support, spans the second portion of the axle support, and has a sliding fit with the second portion of the axle support, and where at least a portion of the second guide system is configured to contact the first wheel to hold the wheel at a substantially fixed position away from the second portion of the axle support; an attachment structure connected to the axle support and configured to attach the skate to a foot of a user; and at least one other wheel associated with the attachment structure.
